Question
EMPLOYMENT For Exercises 27–30, use the graph that models the unemployment rates from 1975–2000.
If this graph was modelled by a polynomial equation, what is the least degree the equation could have?
Step-by-Step Solution
Verified Answer
The least degree the equation could have is 5.
1Step 1. Given
Given graph is:
2Step 2. To determine
If this graph was modelled by a polynomial equation, what is the least degree the equation could have?
3Step 3. Calculation
From the graph:
The graph is going upwards on the left side and downwards on the right side. Since it is going on two different sides on both ends so it must be an odd degree polynomial equation.
There are 4 turning points. So, the least degree of the polynomial equation is .
