Question

The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on the parabola. Which equation can be used to model the image of the lens?
y = (x – 2)(x + 3)
y = (x – 2)(x + 3)
y = (x + 2)(x – 3)
y = (x + 2)(x – 3)

Answer 1

help please

Answer 2

"crosses the x-axis at -2 and 3" is the same as the roots are at x=-2 and x=3
this should eliminate 2 of your choices, then try subsitituting in x=-1 and y=2 in order to determine which of the remaining 2 answer is the correct one

Answer 3

so would it be the first one
