Question

How would you do this? I’m lost.

Answer 1

Find the x intercepts by setting each x to equal 0:

(4-x)=0

4 -4 = 0

First x intercept = (4,0)

(x+2) = 0

-2 + 2 = 0

Second x intercept = (-2,0)

Now find the Y intercept by setting the x's to 0 and solve for y:

y = (4-0)(0+2)

y = 4*2

y = 8

The Y intercept is (0,8)

Now find the graph the the parabola crosses the x axis at -2 and 4 and also crosses the Y axis at 8.

Graph A is the correct one.
