Question

YOo pls help !
g(a)=2a-1
h(a)=3a-1
find (g•a)(-4)

Answer 1

For this, you will be multiplying g(-4) and h(-4) together.

`(g*h)(-4)=(2(-4)-1)(3(-4)-1)`

Firstly, do the multiplications within the parentheses:
`(g*h)(-4)=(-8-1)(-12-1)`

Next, do the subtractions:
`(g*h)(-4)=(-9)(-13)`

Lastly, multiply -9 and -13, and your answer should be
`(g*h)(-4)=117`
