You can think of an <em>inverse </em>function as a function that “unwraps” x from whatever operations are attached to it. In the case of F(x) = √x, we can ”unwrap” x by squaring it. This narrows our options down to either A or D. Keep in mind that since there are no real number solutions to the square root of a negative number, we need to limit our domain to non-negative values. In other words, x ≥ 0. With that restriction, our answer is A.
Answer:
50,000 miles
Step-by-step explanation:
First,
If C is the annual operating cost, you can modify/substitute into the equation,
21,100 = 0.37m + 2600
Second, solve the equation for m,
0.37m = 18,500
m = 50,000
