Question

Given that G(x)=x-3/x+4 find each of the following

G(5)
G(3)
G(-4)
G(-10.25)
G(x+h)

Answer 1

Looks like you're doing some pre-calc here... The way to handle these is in the equation for g(x), replace x with each of the values given. g(5) would be this:
`(5-3)/(5+4)` which is 2/9. Do that for all the number values. When you get to the last one, that's done the same way except you won't get a number answer like you did in the others. Instead of replacing x in g(x) with a number value, you're replacing it with (x+h):
`g(x+h)= ((x+h)-3)/((x+h)+4)`. That's all you can do with that one. You don't have to leave the parenthesis in there; I just did so you can see the (x+h) they asked you to sub in.
