f(x) = 7x - 5
A) -75
B) -65
C) 65
D) 90
I chose a is that correct

Answer 1

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.
