Answer:

A is correct.

B is actually 50.

C is actually 62.

Step-by-step explanation:

Sadly, I don't know what D is, but I can tell you that the 1 in h(x) will always stay the same. Good luck on your test! :-D

Answer:

a. 6

b. 50

c. 62

d. |1 - 7g(x) |

Step-by-step explanation:

a. h(1) = |1 - 7(1)|   =  | - 6 |  =  6

b. h(-7) = |1 - 7(-7)|  = |1 + 49|  =   | 50 |  =  50

c. h(9) = |1 - 7(9)|  = |1 - 63|  =  | -62 |  =  62

d.  The composition of function h with function g is written as h ∘ g and is defined as (h ∘ g )( x ) = h( g( x )).  

Therefore, given h( x ) = | 1 - 7x |:  

h ∘ g if g(x ) = h(g( x )) = | 1 - 7g(x ) |

By the way, when you deal with composition of functions, you can do the following steps:

   1. Evaluate g(x) first.

   2. Then use g(x) as the input for h.
