Math Problem Statement

F(x) = 7x^5

Solution

The function F(x)=7x5F(x) = 7x^5 represents a polynomial function. Here are some key points related to it:

Properties of F(x)=7x5F(x) = 7x^5:

  1. Degree: The degree of the function is 55, as the highest power of xx is 55.
  2. Leading Coefficient: The coefficient of the highest degree term (x5x^5) is 77, making 77 the leading coefficient.
  3. Behavior at Large x|x|: As xx \to \infty, F(x)F(x) \to \infty. As xx \to -\infty, F(x)F(x) \to -\infty. This is due to the odd degree and positive leading coefficient.
  4. Derivative: The derivative of F(x)=7x5F(x) = 7x^5 is F(x)=35x4F'(x) = 35x^4, which represents the slope of the function at any point xx.
  5. Integral: The indefinite integral of F(x)=7x5F(x) = 7x^5 is: F(x)dx=7x66+C,\int F(x) \, dx = \frac{7x^6}{6} + C, where CC is the constant of integration.
