Question

f(x)=2x-7 .... for which values of x is f(x)>0?

Answer 1

f(x)>0
2x-7>0
Solve for x.
Does that help? @laurenn_marie7

Answer 2

so x > 7/2 ?

Answer 3

The answer part says: for every x in the interval ___, f(x) > 0. so would I just put 7/2 where the blank is? @ajprincess

Answer 4

(7/2,infinity)

Answer 5

For any values between 7/2 and infinity f(x)>0.
so the interval is (7/2,infinity)

Answer 6

thank you!! so for f(x)<(or equal to) g(x) I would just substitute f(x) and g(x)?
