<em>The Graph is shown below</em>
Step-by-step explanation:
<u>The Graph of a Function</u>
Given the function:

It's required to plot the graph of g(x). Let's give x some values:
x={-2,0,2,4,6}
And calculate the values of y:

Point (-2,-24)

Point (0,-6)

Point (2,0)

Point (4,-6)

Point (6,-24)
The graph is shown in the image below
The standard form is 21x-y-7=0
C is correct because A is 2.82 and B is 2.8
