Question 7 (Multiple Choice Worth 1 points)

What are the x– and y–intercepts of the quadratic equation y = 2x2 – 8x + 6?

x–intercepts: (–3, 0) and (–1, 0)
y–intercept: (0, 3)

x–intercepts: (–3, 0) and (–1, 0)
y–intercept: (0, 6)

x–intercepts: (–3, 0) and (–1, 0)
y–intercept: (0, 3)

x–intercepts: (3, 0) and (1, 0)
y–intercept: (0, 6)

Question 8 (Multiple Choice Worth 1 points)

Which of the following is the vertex of the quadratic equation y = –4(x + 6)2 + 2?

(6, 2)

(–6, 2)

(6, –2)

(–6, –2)

Question 9 (Essay Worth 2 points)

Describe the diff

Answer 1

Part1) for y intercept, x=0
So y intercept is (0,6)
for x intercept, y=0
So solving the quadratic equation, you get two x intercepts
x= (1,0) and (3,0)

Answer 2

thanks for that can you do the others aswell?

Answer 3

8) vertex is -4

Answer 4

but that not a choice for some reason..
