An expression is shown below:

f(x) = −16x2 + 24x + 16

Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)

Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)

(10 points)

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.

the answer is simply just 6n add the two together as they have an n
