# How do you find the vertex and the intercepts for f(x)=(x+3)^2?

Feb 20, 2017

$y$ intercept=(0,3)
$x$ intercept and also vertex=(-3,0)

#### Explanation:

When you have a question like this, it is very easy to find the vertex of the curve. We know that the line has equal roots so the vertex is -3 by making ($x$+3)=0. This also gives you the $x$ intercept.

To find the $y$ intercept, make $x$ equal zero. You get the equation:

$y$=$x$(0)+3 hence $y$=3
