To solve this fraction we have to reduce to the same denominator, but prior to reducing, note that one of the denominators x²-4 could be expanded to:
(x-2)(x+2)   [remember a² - b² =n(a-b)(a+c)]

Let the denominator be (x-2)(x+2),

2/(x-2)(x+2) -(x-2)/(x-2)(x+2) = 3(x+2)/ (x-2)(x+2) ==>

2 -(x-2) = 3x+6 ==>2-x+2 = 3x+6 ==> x=-4/6 ==> x= - (1/2)

Describe how the graph of g(x) is related to the parent function f(x).
Nataly [62]

Answer:

C

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here f(x) = 4x and g(x) = 4x - 2

That is g(x) is the graph of f(x) shifted 2 units down
