Question

If t(x)=3-2x and g(x)=1/x+5, what is the value of (f/g)(8)

Answer 1

Explanation:

I'll assume you meant f(x) = 3 - 2x and not t(x) = 3 - 2x

`(3 - 2x)/( (1)/(x + 5) ) * 8`

`((3 - 2x) * ( (x + 5)/(1) )) * 8`

`((3 - 2x)(x + 5)) * 8`

`( - 2 {x}^(2) - 7x + 15) * 8`

`( (f)/(g)) * 8 = - 16 {x}^(2) - 56x + 120`
