Answer:
<em>Choice D.</em>
Step-by-step explanation:
Vertical line test for functions:
If a vertical line drawn anywhere on the graph intersects the graph in more than one point, it is not a function.
If you draw a vertical line passing through any point between x = -4 and x = 4, the line will intersect two points on the circle. The relation fails the vertical line test. That shows that this relation is not a function.
Answer:
48x^2-48x+12
Step-by-step explanation:
3(area of square)
3(w^2)
3((4x-2)^2)
3(16x^2-16x+4)
48x^2-48x+12
