Find f (-10).

f (x) = 7x - 5

A) - 75

B) - 65

C) 65

D) 90

I chose a is that correct

Answer: - 75

Explanation: In this problem, we're given the function f (x) = 7x - 5 and we're asked to find f (-10).

To find f (-10) or the value of the function when x = - 10 we simply substitute - 10 in for x in our function.

So we have 7 (-10) - 5 or - 70 - 5 which equals - 75.

So f (-10) or the value of the function when x = 10 is - 75.

Since your answer to this problem was a, your answer is correct.
