Given the function g(x)=2x²-12 ,find g(-3).

g(-3) = -30

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

g(x) = 2x² - 12

g(-3) is x = -3

Step 2: Solve

Substitute:                    g(-3) = 2(-3)² - 12Evaluate:                       g(-3) = -2(9) - 12Multiply:                        g(-3) = -18 - 12Subtract:                       g(-3) = -30

On monday,mrs.wise bought 3 lbs of apples at $4per lb= 4*3=$12on tuesday ,20%off and she buy 5 lbs of apples = $4-20%=3.20*5lb=$16example: other wise when she buy 5lbs on monday she have to spend 4*5=20

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
