Answer:
1. 7
Step-by-step explanation:
First, replace f(x) with y.
So we have now:
y = 3x + 1
Next, switch the x and y.
We get:
x = 3y + 1
Finally, solve for y.
3y = x - 1
y = x/3 - 1/3
So, we have f(x) = 3x + 1, and the inverse of this function is:
Answer:
$1792
Step-by-step explanation:
The problem statement tells you that the 8% of her salary that Carol puts in her 401(k) plan is not subject to income tax. Therefore, she is taxed on .08·64000 = 5120 less income than is Sheryl, so saves
