Given f(x) = 10 -2xfind f(7). –4 3 7 56
strojnjashka [21]

Answer: f(7)=-4

Step-by-step explanation:

1. You have the following function given in  the problem:

f(x)=10-2x

2. Then, to find f(7) asked in the exercise, you only need to substitute x=7 (which is the input value) into the given function.

3. Therefore, keeping the above on mind, you obtain that f(7) is:

x=7

f(7)=10-2(7)

f(7)=10-14

f(7)=-4
