Question

For the function g(x) = -x-3, find g(8a - 16).=-gx= x, g.

Answer 1

The given function is

`g(x)=(1)/(8)x-3`
`\text{Repalce }x=8a-16\text{ to compute }g(8a-16)\text{.}`

`g(8a-16)=(1)/(8)(8a-16)-3`

`=(1)/(8)*8a-(1)/(8)*16-3`

`=a-2-3`

`=a-5`

Hence the required answer is

`g(8a-16)=a-5`
