Question

y = – (x + 3)2+ 1

y = – (x – 3)2+ 1

y = (x – 3)2+ 1

y = (x + 3)2+ 1

Answer 1

What is the equation of the graph below?

Answer 2

The vertex general form is:

y = a(x - h)^2 + k

The parabola opens upwards, so you know that "a" is positive, which limits your choices to "c" and "d".

The low point is when x = 3, so the part in the parentheses is "x - 3". The low point value for y is "1", so k = "+1"

So, you can put it all together and easily choose between "c" and "d". And do get in the good and necessary habit of using "^2" instead of "2" as otherwise ALL your choices are wrong.

Answer 3

what so ur telling me all my choices are wrong then what am i supposed to choose?

Answer 4

You're not listening.

You first correct all your choices to "^2" instead of "2" for the exponent. Then you do the analysis and choose based on the work I did for you already.

Answer 5

so c& d look like good candidates u said?

Answer 6

@tcarroll010 ??

Answer 7

yes?

Answer 8

It's all in my first post.

Answer 9

so the answer is c right?

Answer 10

Yes.

Answer 11

Provided that you change "2" to "^2"
