Let f(x)=8x−6. What is the value of f(1/2)?

Question

Answer 1

Substitute in 1/2 for x into the equation:

f(x) = 8x - 6

f(1/2) = 8(1/2) - 6

f(1/2)= 4 - 6

f(1/2) = -2

Answer 2

All you have to do in this case is replace x by 1/2 in f(x). Thus getting f(1/2)=8(1/2)-6=8/2-6=4-6=-2. The answer will be -2.
