If h(x) = 4x - 8 and j(x) = -x, solve h[j(3)] and select the correct answer below.
-36, -20, 1, 4
Solution:
It is given that
h(x) = 4x - 8
j(x) = -x
We know that h[j(x)], is a composite function.
(h o j) (x) = h (j(x))
Here
h(j(3)) = h(-3)
h(j(3)) = [4(-3) - 8]
By further simplification
h(j(3)) = -12 - 8
h(j(3)) = -20
Therefore, h(j(3)) is -20.
If h(x) = 4x - 8 and j(x) = -x, solve h[j(3)] and select the correct answer below.
-36, -20, 1, 4
Summary:
If h(x) = 4x - 8 and j(x) = -x, h(j(3)) is -20.
