Graph Using X-Intercepts | quadratic-unit

Graphing

For Graph using x-intercepts. you will need to know the Quadratic Formula as well as how to get the Maxima and Minima.

I will post a few questions below for you to try out and graph it. the answers will be below.

y=-2x^2+3x+4

y=-3x^2+7x+1

y=6x^2+5x-3

Anchor 1

y=-2x^2+3x+4:

x-intercepts:(-0.8,0) and (2.3,0)

vertex: (0.8,5.1)

y=-3x^2+7x+1:

x-intercepts:(-0.2,0) and (2.5,0)

vertex: (1.2,5.1)

y=6x^2+5x-3:

x-intercepts:(-1.2,0) and (0.4,0)

vertex: (-0.4,-4)
