Please help this is due soon and if I don’t get it in my teacher will only give me half credit :(

A) x = (-1/2) and x = 2,

B) x = 3/4, y= 25 (3/4,25) Its a maximum because the vertex is higher than the x coordinates. What i mean by that is that the vertex is at y coordinate 25 and then at x= 2, y = 0 it means its a maximum.

C) You have the vertex and the y- intercepts. You have 3 points in order to draw the graph.

Step-by-step explanation:

Note that in order to find number 1, you will have to use the quadratic formula. However, I cheated and used wolframalpha but you can also use it to double check. I am sure that if you used the quadratic formula you will get the same roots.

Hope this helps.
