Question

If h(x) = 4x − 8 and j(x) = −x, solve h[j(3)] and select the correct answer below. (1 point) −20 −36 1 4

Answer 1

h[j(3)] = -20

Explanation:

We need h(j(3)). First find j(3)

j(x) = -x, so

j(3) = -(3) = -3

Now find h(-3)

h(x) = 4x - 8, so

h(-3) = 4(-3) - 8

h(-3) = -12 - 8 = -20

So h[j(3)] = -20

Answer 2

Correct answer is:

-20

Explanation:

h(x) = 4x − 8 and j(x) = −x

We have to solve h[j(3)]

j(3)= -3

So, h[j(3)]=h[-3]

= 4(-3)-8

= -12-8

= -20

Hence, Correct answer is:

-20
