Concept explainers
To Match: The given polynomial function with its graph.
For the polynomial function
Given:
Calculation:
For any polynomial function
Here the function
So, the limits are
Find the local maximum and local minimum:
Find the first derivative of the function
Find the second derivative of the function:
To find the local maximum and minimum values of the function, set the derivative equal to
Use the quadratic formula to find the solutions:
Substitute the values
Simplify the equation:
The local maximum and local minimum are:
The function
Find the zeros at
intercept:
Graph each side of the equation
The function has zeros at
Thus, for the polynomial function
