Question

What are the x– and y–intercepts of the graph of y = 2x2 – 8x – 10?


x–intercepts: (–1, 0) and (–5, 0)
y–intercept: (0, 5)
x–intercepts: (1, 0) and (–5, 0)
y–intercept: (0, 10)
x–intercepts: (–1, 0) and (5, 0)
y–intercept: (0, 5)
x–intercepts: (–1, 0) and (5, 0)
y–intercept: (0, –10)

Answer 1

You can find the x intercept by letting y = 0 and you can find the y intercept by letting 2 = 0.
Can you do that?

Answer 2

well the answers are above but im not sure of the answer

Answer 3

Take the equation and replace y with 0 and you get: 2x^2 -8x-10=0
Now factor out the common factor of 2 and tell me what you get.

Answer 4

i get question one as the answer is that correct?

Answer 5

No

Answer 6

If you replace x with -5, you will not get 0

Answer 7

Also if you replace x with 0 you will not get 5

Answer 8

So can you factor out the 2 like I said?

Answer 9

ohh the answer is c?

Answer 10

Please answer my question. You are guessing.

Answer 11

noo im really not

Answer 12

So how did you get C?

Answer 13

so its b?

Answer 14

i dunno im really confused
