Question

The function g and h are defined by
g(x) 4x+1/3x-2 and h(x)5x-2

Calculate g(0)
4(0)+1/3(0)-2 = -1/2

Calculate h(1/5)
5(1/5)-2 = -1

Determine the value of gh(1/5)
4(5(1/5)-2)
(3(1/5)-2)= 4(-1/-1.4)= 2.85 is this right??

Answer 1

correct on the first two.
On the last
Determine the value of gh(1/5)
4(5(1/5)-2)
(3(1/5)-2)= 4(-1/-1.4)= 2.85 I think this line is wrong.
remember h(1/5) is -1, so you are looking for g(-1)
<b> g(-1)=4(-1) + 1/(-3-2)=-4-1/5=-4 1/5
</b>
