Question

one more question for the night. Okay here goes...
Which graph matches the function y = √2x+6

Answer 1

The radicand 2x + 6 = 0 when x = -3.

2x + 6 = 0
2x = -6
x = -3

Any value less than -3 will make the radicand negative which can't happen for a graph in the real number system.

Look for a graph that begins at -3 and increases (rises on the plane) as x increases.

The graph will cross the y-axis when x = 0. Y = square root of 6 then.

I see a graph that looks that way. See if you do and post the answer here. I'll check.

Answer 2

okay. give me a min.

Answer 3

okay, take your time. I believe you can choose the correct one.

Answer 4

It would be graph 2 right?

Answer 5

Yes, it is.

Answer 6

well thank you very much!! I really appreciate the help! And I love the high-five. ;)
