Question

If f(x) = 2x − 4 and g(x) = x2 − 4x, find f(4).

Answer 1

Just substitute 4 for x in f(x), which means..
f(4)=2*4 -4..

Answer 2

Would that be f=1?

Answer 3

solve this..
(2*4)-4, where * sign means multiplication..

Answer 4

f=4?

Answer 5

yup. f(4)=4..

Answer 6

If f(x) = 2x − 4 and
g(x) = x2 − 4x, find f(4).
i'll solve it for you @Nikkib312

for f(x) if f=4 then put it:
f(x) = 2x-4
f(4) = 2(4)-4
f(4) =8-4
f(4) =4
so what about g(x)?
