Question

The function f is given by f(x) = 10x + 3 and the function g is given by g(x) = 2×. for each question, show your reasoning

Answer 1

Answer:

i got you :D

Step-by-step explanation:

f(x)= 2x²+4x-6 and g(x)=2x-2, find each function

1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)

First factor both top and bottom:

(2x-2)(x+3)÷(2x-2) = x+3

2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->

2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:

2a^2+8a+8+4a+2, combine like terms

2a^2+12a+10
