Question

Graph the quadratic function f(x) = 2(x - 3)2 - 2 and select all of the following which are true.maximum at (-3,-2)minimum at (3,-2)x-intercept at (2,0)x-intercept at (4,0)y-intercept at (0, -16)

Answer 1

Graph:

By looking at the graph we can see that:

It opens upwards, so it has a minimum at (3,-2)

I crosses the x axis at x=2 and x=4

x- intercepts at (2,0) and (4,0)

It doesn't cross the y axis
