Ccalculate the value of f(4) for this function. f(x) = -(x-7)+3 i know the anwser is f(4)=6 but how?
Tasya [4]

Answer:

See below

Step-by-step explanation:

we have f(x) = -(x-7) + 3

and we want to find f(4)

essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.

So for f(x) = -(x-7) + 3

To find f(4) we replace all x's with 4

f(4) = -(4-7) + 3

we now evaluate

==> subtract 7 from 4

f(4) = -(-3) + 3

==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )

f(4) = 3 + 3

==> add 3 and 3

f(4) = 6
