Which functions are not rational functions?
Functions that are not rational functions include trigonometric functions (such as sine, cosine, and tangent), exponential functions (such as \(e^x\)), logarithmic functions (such as \(\log(x)\)), and radical functions (such as \(\sqrt{x}\)). These functions involve operations like trigonometric ratios, exponentiation, logarithms, and roots, which cannot be expressed as a ratio of two polynomials.
-
What are inverse functions of power functions?
The inverse functions of power functions are typically radical functions. For example, the inverse of a square function (f(x) = x^2) would be a square root function (f^(-1)(x) = √x). In general, the inverse of a power function with exponent n (f(x) = x^n) would be a radical function with index 1/n (f^(-1)(x) = x^(1/n)). These inverse functions undo the original power function, resulting in the input and output values being switched.
-
What are power functions and root functions?
Power functions are functions in the form of f(x) = x^n, where n is a constant exponent. These functions exhibit a characteristic shape depending on whether n is even or odd. Root functions, on the other hand, are functions in the form of f(x) = √x or f(x) = x^(1/n), where n is the index of the root. Root functions are the inverse operations of power functions, as they "undo" the effect of the corresponding power function. Both power and root functions are important in mathematics and have various applications in science and engineering.
-
What are inverse functions of exponential functions?
Inverse functions of exponential functions are logarithmic functions. They are the functions that "undo" the effects of exponential functions. For example, if the exponential function is f(x) = a^x, then its inverse logarithmic function is g(x) = log_a(x), where a is the base of the exponential function. In other words, if f(x) takes x to the power of a, then g(x) takes a to the power of x.

What are polynomial functions and what are power functions?
Polynomial functions are functions that can be expressed as a sum of terms, each of which is a constant multiplied by a variable raised to a non-negative integer power. For example, f(x) = 3x^2 - 2x + 5 is a polynomial function. Power functions are a specific type of polynomial function where the variable is raised to a constant power. They can be written in the form f(x) = ax^n, where a is a constant and n is a non-negative integer. For example, f(x) = 2x^3 is a power function. Both polynomial and power functions are important in mathematics and have various applications in science and engineering.

'Parabolas or Functions?'
Parabolas are a specific type of function that can be represented by the equation y = ax^2 + bx + c. Functions, on the other hand, can take many different forms and can represent a wide variety of relationships between variables. While parabolas are a type of function, not all functions are parabolas. Therefore, the choice between parabolas and functions depends on the specific relationship being modeled and the form that best represents that relationship.
-
How do parameter variations and power functions look in functions?
Parameter variations in functions can be represented by changing the coefficients or constants in the function equation. For example, in a linear function y = mx + b, varying the values of m and b will change the slope and y-intercept of the function. Power functions, on the other hand, have the form y = ax^n, where a is the coefficient and n is the exponent. Varying the values of a and n will change the steepness and curvature of the power function. Overall, parameter variations and power functions can be visually represented as changes in the shape, slope, and position of the function graph.
-
What is the difference between exponential functions and polynomial functions?
Exponential functions have a variable in the exponent, while polynomial functions have a variable raised to a constant power. Exponential functions grow at an increasing rate as the input variable increases, while polynomial functions can grow at a decreasing rate or remain constant. Additionally, exponential functions never reach zero, while polynomial functions can have roots where the function equals zero.
