If h(x) = 4x - 8 and j(x) = -x, solve h[j(3)] and select the correct answer below.
-36, -20, 1, 4
Solution:
Given h(x) = 4x – 8 and j(x) = -x
To find: h(j(x)), which is a composite function.
By putting x=3 in j(x), we get j(3)= -3
By putting x=j(3)= -3 in h(x), we get as follows j(3)= -3
h[j(3)] = h(-3)
=4(-3) -8
= -12 -8
= -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, by solving h[j(3)], the correct answer is -20.
