# What is the vertex of y= -3(x-2)^2-1?

Apr 9, 2018

$\left(2 , - 1\right)$

#### Explanation:

This equation is in vertex form

$y = a {\left(x - h\right)}^{2} + k \rightarrow$ $h , k$ represents the vertex

In this equation, $- 3$ represents $a$, $2$ represents $h$, and $- 1$ represents $k$.

$h , k$ in this case is $2 , - 1$
