Answer:
The correct answer is,
f(7) -4
Step-by-step explanation:
It is given that,
f(x) = 10 - 2x
<u>To find f(7)</u>
To find f(7) we have to put 7 instead of x in f(x).
Here f(x) = 10 - 2x,
Step 1: substitute the value x = 7 we get ,
f(7) = 10 - (2 * 7)
= 10 - 14 = -4
Therefore we get the answer f(7) = -4
The correct answer is first option.
1. You have the following function given in the problem:
2. Then, to find asked in the exercise, you only need to substitute (which is the input value) into the given function.
3. Therefore, keeping the above on mind, you obtain that is:

C. 3x2 − 3x − 60
3(x + 4) (x - 5) = (3x+12) (x-5)
(3x+12) (x-5) = 3x2+12x-15x-60
3x2+12x-15x-60 = 3x2 − 3x − 60
