Given f(x) = 10 -2xfind f(7). –4 3 7 56

Step-by-step explanation:

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:

The correct answer is,

f(7)  -4

Step-by-step explanation:

It is given that,

f(x) = 10 - 2x

To find f(7)

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.
