For this case, the first thing we must do is define variables.
We have then:
x: number of years
y: total salary
For company 1 we have:
For company 2 we have:
By the time both salaries are equal we have:
From here, we clear the value of x.
We have then:
Answer:
Brenda's salary would be the same with both companies in 8 years.
The function that could be a stretch of the exponential decay function shown on the graph is B. f(x) = One-half(6)x.
<h3>How to illustrate the function?</h3>From the information given, it can be seen that function A is a monotonically increasing function.
Also, it can be seen that C and D don't pass through (0, 1).
Therefore, the function could be a stretch of the exponential decay function shown on the graph is B.
