Read some notes on reflection. If it asks to reflect it on the x-axis youre going to reflect it either on the bottom or top plane. If it asks to reflect on y-axis youre going to reflect it on either the left or right plane.
<h3>
Answer: c = 7/4</h3>
================================================
Work Shown:
Compute the function value at the endpoints

With a = -5 and b = 4, we have

So,

Use algebra to solve for c

2x^(3)y+7xy-3x^(2)-12y
is in standard form
