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

h[j (2) ] = - 13.

Step-by-step explanation:

Given : If h (x) = 3x - 1 and j (x) = - 2x,

To find : solve h[j (2) ].

Solution : We have given

h (x) = 3x - 1 and j (x) = - 2x

For x = 2,

j (2) = - 2 (2).

j (2) = - 4.

h[j (2) ] = h (-4).

h (4) = 3 (-4) - 1.

h (4) = - 12 - 1.

h[j (2) ] = h (4) = - 13.

h[j (2) ] = - 13.

Therefore, h[j (2) ] = - 13.

h[j (2) ] = -13

Step-by-step explanation:

The first step is to solve j (2) by putting x=2 into j (x)

j (2) = - 2 (2) = - 4

Now we put x = - 4 into h (x)

h (-4) = 3 (-4) - 1

h (-4) = - 12-1 = - 13

h[j (2) ] = -13
