Question

Graph the function. G(x)=2(x+2)(x+6)

Answer 1

Explanation:

Distribute 2(x+2):

2(x) + 2(2) = 2x + 2

Use the FOIL method to multiply (2x + 2)(x+6)

(2x + 2)(x+6)

2x(x) = 2
`2x^(2)`

2x(6) = 12x

2(x) = 2x

2(6) = 12

2
`2x^(2)` + 12x + 2x + 12 = 2
`2x^(2)` + 14x + 12

Graph the following equation on a graphing calculator, and then you should know how to graph it on paper.
