How do i find the vertex of this equation.?

Question

i need help with this question could you please show me how to find the vertex of an equation please show step by step.

i am not cheating i want to know this because everytime ask my teacher she ignores me and goes eats cottage cheese.

here is the example. y= (x+3)^2 -1

Answer 1

In general: y = a*(x - c)² + t

1. To find x, the term in brackets has to be 0.

2. To find y, just ignore a*(x - c)² and say: y = t.

Here:

(x + 3) = 0
-3 + 3 = 0

x = -3

y = -1

So the vertex is (-3|-1).
