Answer to Problem 7PS
Explanation of Solution
Given information:
For each part, write a cubic function of the form
Calculation:
We have given a function to create the cubic equation. The function is
This equation satisfies
Now the second statement says that the graph rises at the right.So the coefficient of the highest degree should be positive then. So we have to choose
So the equation is
