You plug 4/5 into f(x)=5x-4,
it's 0, and you plug 0 into g(x)=x^2-1,
it's -1.
Answer: -1.
ONE OF THE UGLIEST: WHO DO YOU THINK YOU ARE? BETTER GET YOUR STUPID A$$ OUT OF HERE!
(5*4/5-4)^2-1
It's just saying that you take g(x) (x^2-1) and you plug in f(x) (5x-4) to where the x is in g(x)
f(4/5) means that you plug in 4/5 for x.
therefore, (5(4/5)-4)^2-1 = -1
Do f(4/5) first. Then put that solution into g(x).
just cause sun can figure out the answer doesint mean shes powerful
