# What is the sum of the x-intercepts of the graph of the quadratic function y=x^2-4x-12?

$4$

#### Explanation:

The sum of the roots of any quadratic is given by the formula:

$\text{sum of roots } = - \frac{b}{a}$

Therefore, in this case we have:

$\text{sum of roots } = - \frac{- 4}{1} = 4$

So the sum of the x-intercepts of the graph is $4$.
