Question

Describe the graph that would be used to solve

the equation -x2 + 4 = x + 2 using a system of
equations. How will you use the graph to find the
solution(s)?

Answer 1

The graph contains a parabola that opens down and has a vertex at (0, 4).

The graph contains a line that has a slope of 1 and a y-intercept of 2.

The solutions are the x-coordinates of any intersection points.

Answer 2

A quadratic graph whose equation is....

x2 + x - 2

Explanation:

Firstly create your equation by moving all variables to one side....x2 + x + 2 - 4.

Then after drawing the graph...the solutions to the equation are the points at which the graph intercepts with the x-axis of the cartesian plane
