Question

What is the vertex of the graph of y = –4(x + 2)2 + 5?
Can someone show me how to solve this using steps.

Answer 1

the last two is square ... i guess.

Answer 2

oh nvm you mean -4(x+2)^(2) + 5

Answer 3

else there wouldn't be a vertex.

Answer 4

Yes it's squared, my bad.

Answer 5

y = 5
x = -2

Answer 6

Can you show me how you solved it?

Answer 7

4(x + 2)^2 = 0 for x

since this will be zero, the remaining will be 5
easy trick

try for this one
y = 5(x-3)^2-6

Answer 8

How come you took off the negative for the 4?

Answer 9

I don't understand :/
