How do I solve this equation and find the vertex, axis of symmetry, y intercept and the domain and range?

Answer & Step by Step :

The vertex is    (2, -11)

The axis of symmetry is    x=2

The y-intercept is    (0, 1)

The Domain and Range are in the picture

stuff that WILL HELP YOU STUDYING AND CHECKING YOUR WORK (I PROMISE)

I used these to find your answer quickly^^^

Be sure to actually know the material because I promis you, you WILL see these again on countless amounts of tests

  - search m-a-t-h-w-a-y

  - search: d-e-s-m-o-s

( won't let me type them out by don't add these '-' when searching them up)

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
