SOMEONE PLEASE HELP ME!!!if f(x)=x^2+2x-3 and g(x)=x^2-9, find (f/g)(4) and (f+g)(4)
Accepted Solution
A:
Replace x in each equation with 4:f(x) = x^2 +2x-3 = 4^2 + 2(4) -3 = 16 + 8 -3 = 21g(x) = x^2-9 = 4^2 -9 = 16-9 =7Now you have values for f(x) and g(x) now you can solve for f/g and f+g:f/g = 21 / 7 = 3f+g = 21 + 7 = 28
