Question

What is the equation of the graph below?

Answer 1

y = - (x + 2)2 + 2

y = - (x - 3)2 + 2

y = (x - 2)2 + 2

y = (x + 3)2 + 2

Answer 2

you can eliminate the last 2 options as the graph is facing down meaning that the x^2 is negative not positive

Answer 3

ok thank you. thats a start

Answer 5

now do you know where the vertex is?

Answer 6

can you identify the vertex...?

if you can the general from is

\[y = (x - h)^2 + k\]

where (h, k) is the vertex

Answer 7

oh ok well then it has to be the first option

Answer 8

well look again

Answer 9

well not quite

Answer 10

thanks for all your help!! :D

Answer 11

the vertex is at 3,2 so it leaves the second option

Answer 12
