sketch the graph of these quadratics, labelling all significant points. round the x-intercepts to
two decimal places.
a y = 2x2 + 8x - 5

Step-by-step explanation:

Given the quadratic function

To plot the graph of this function, find the vertex of parabola, x- and y- intercepts.

1. The vertex:

2. y-intercept:

3. x-intercepts:

4. The leading coefficient is 2 > 0, then parabola goes in positive y-direction
