Question

What is the range of the graph of y = 3(x – 3)^
2 + 4?

Answer 1

The range of \[\large y=a(x-h)^2+k\] is \[(-\infty,k]\] if \[a<0\]
-------------

The range of \[\large y=a(x-h)^2+k\] is \[[k,\infty)\] if \[a>0\]

Answer 2

yeah i have no idea what this is, can you just give me the answer so i can finish this exam

Answer 3

That's the general formula for a quadratic in vertex form, which is what you have there. In this case, h=3 and k=4

What is the value of 'a'?

Answer 4

ooooh, i get it never mind, thx alot, this was really helpful
