Answer:

Option (b) is correct.

h[j(3)] = -20

Step-by-step explanation:

Given : h(x) = 4x − 8 and j(x) = −x

We have to solve for h[j(3)] and choose the correct option from given options.

Function composition is when one function is inside of another function and we evaluate the value of a function by plug one into into another function.

Consider , the given functions h(x) = 4x − 8 and j(x) = −x

h[j(3)] is defined as h[j(x)] at x = 3

First we find h[j(x)] and then substitute x = 3 .

h[j(x)] = h(-x)

Thus, find h(x) when x = -x

We get , h(-x) = 4(-x) − 8

Now put x = 3, we get,

h[j(3)]=h[-3] = 4(-3) - 8 = -12 - 8 = -20

Thus, h[j(3)] = -20

Option (b) is correct.

If h(x) = 3x − 1 and j(x) = −2x, solve h[j(2)] and select the correct answer below.
