What is the strongest local change of functions?
The strongest local change of functions occurs at a point where the function has a local maximum or minimum. At these points, the function experiences a significant change in direction, either increasing or decreasing rapidly. These points are critical in analyzing the behavior of the function and understanding its overall shape and characteristics. Additionally, these points are important in optimization problems as they represent the highest or lowest values of the function in a given interval.
-
Are all global extrema also local extrema of polynomial functions?
No, not all global extrema are also local extrema of polynomial functions. A global extremum is a point where the function has the highest or lowest value over its entire domain, while a local extremum is a point where the function has the highest or lowest value in a specific neighborhood. A polynomial function can have global extrema that are not local extrema if the function continues to increase or decrease beyond the neighborhood of the extremum.
-
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.
-
Are there third-degree functions that have exactly one local extremum?
Yes, there are third-degree functions that have exactly one local extremum. For example, the function f(x) = x^3 has exactly one local extremum at the point (0,0). This is because the function has a critical point at x=0 where the derivative changes sign from negative to positive, indicating a local minimum.

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.
-
Are all global extremum points also local extremum points of polynomial functions?
No, not all global extremum points are also local extremum points of polynomial functions. Global extremum points are the highest or lowest points on the entire function, while local extremum points are the highest or lowest points within a specific interval. A polynomial function can have global extremum points that are not local extremum points if the function continues to increase or decrease beyond the local extremum point.
