Concept explainers
a.
To write a cubic function by using the form
a.
Answer to Problem 7PS
Explanation of Solution
Given information:
Use the form
Passes through the point
Calculation:
Here, we have given a function to create the cubic equation. The function is
Now, this equation satisfies
Now, in the second statement it is given that the graph rises at right. So, the coefficient of the highest degree should be positive then. Thus, we have to choose
Hence, the equation will be
