I need help on these two problems my teacher gave us. I'm already failing the class but I need at least one good grade. Directions: A) f+g(x)
B) f-g(x) C) fg(x) D) F/g(x) Find the domain
I need help on these two problems my teacher gave us. I'm already failing the class but I need at least one good grade. Directions: A) f+g(x)
B) f-g(x) C) fg(x) D) F/g(x) Find the domain
1. f(x)=2x-5 g(x)=2-x
A=
B=
C=
D=
2. f(x)=2x-5 g(x)=4
we are dealing with polynomials here, so the domains for A, B, and C are all real x, that is
for D, obviously the denominator cannot be zero, so the domain is all real x such that
