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

OpenStudy (anonymous):

so x > 7/2 ?

OpenStudy (anonymous):

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

OpenStudy (ajprincess):

(7/2,infinity)

OpenStudy (ajprincess):

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