Question

Given f(x)=2x-5 & g(x)=3x+4, find (f•g)(x)

Answer 1

Answer:

-x-20

Step-by-step explanation:

f(x)=2x-5

g(x)=3x+4

therefore,

(f.g)(x)= (2x-5) (3x+4)

         = (2x.3x)+(2x.4)+(-5.3x)+(-5.4)   [because of distributive property]

         = 6x+8x-15x-20

         = -x-20

hope this helps!
