# What is the domain and range of h(x) = (x^2 - 3x - 4) / (x - 4)?

Feb 19, 2016

#### Answer:

Domain and range are all real values of x and y.

#### Explanation:

We can write:
$h \left(x\right) = \frac{\left(x - 4\right) \left(x + 1\right)}{x - 4} = x + 1$

$y = x + 1$ is a straight line so will go through every value of x and have a value for every y.
