As you can see, every time x increases by 2, y decreases by 5.
So, we have

For f(-2), x will equal -2.
Plug the x-value into the equation:

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

Solve the problem:

f(-2) will equal
1/2.
Answer:
200 miles
Step-by-step explanation:
If n is ten then the expression would change to
2(10)+4
20+4
so your answer would be 24
