Question

Given f(x)=−x+2, find f(4).
a) f(4)=−6
b) f(4)=−2
c) f(4)=2
d) f(4)=6

Answer 1

This operation yields the result of f(4) = -2, which corresponds to option b. To find f(4) for the function f(x) = -x + 2, substitute 4 for x, which gives f(4) = -4 + 2, resulting in f(4) = -2.

Step-by-step explanation:

The student asked to find f(4) given the function f(x) = −x + 2.

To solve for f(4), we need to substitute the value of 4 into the function in place of x. So, f(4) = -4 + 2.

This operation yields the result of f(4) = -2, which corresponds to option b.
