Answer to Problem 31E

  (x−52)2=3(y+252)The graph

Explanation of Solution

Given information: A horizontal axis and passes through the origin and points at (−1,2)and(3,−2)

Calculation:

Use the given points to create a system of equations of the form:

  ax2+bx+c=y

We know c = 0.

  a−b=29a+4b=−2

Solving this system gives you:

  a=13,b=−53,c=0

Completing the square gives you:

  13x2−53x=y(x−52)2=3(y+252)

The graph:
