Find f(-10).
f(x) = 7x - 5
A) -75
B) -65
C) 65
D) 90
I chose a is that correct

-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.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
