Okay, so all this question wants you to do is plug in 2 for x and solve for your output, aka y.
y = -4x² - 8
when x = 2....
y = -4(2)² - 8
y = -16 - 8
y = -24
so, when your input is 2, your output is -24.

Answer: You can't answer this, but here are some guidelines
Step-by-step explanation:
I would love to answer this question (coming from someone who has already completed algebra keystones) but I need to know what the linear equations are before I can. If the functions are reciprocals of one another (the slope is the opposite and the fraction is switched) it is a perpendicular line which means one solution. If the slope is the same but the intercept is different (using y=mx+b) so if b is different but m is the same they are parallel and there is no solution. If they are the same line (same equation) there is infinite solutions. If this doesn't help I would suggest finding graph paper and trying it out and seeing the intersection points.
