Question

I’m so confused please help

Answer 1

a. The x-coordinate of the minimum point of this parabola is halfway between the two roots (-1 and 2). So the x-coordinate here is 1/2, and we have:

`f( (1)/(2) ) = { ((1)/(2) )}^(2) - (1)/(2) - 2 = - 2 (1)/(4)`

So the coordinate of the turning point is (1/2, -2 1/4), or (.5, -2.25).

b. The roots of this parabola are at (-1, 0) and (2, 0).
