Square Root and Cube Root Graphs

Which function matches the graph?

What is the Domain for the graph?

Answer explanation

The domain will be all possible x-values that are greater than the initial point. The x-value of the initial point is -4, so the domain will be all x-values greater than -4.

The domain is defined as all the inputs that are accepted by the function. All possible x-values are the inputs.

Answer explanation

A negative in front of the square root transforms the graph as a reflection over the x-axis.

h=0, k=0, a=1. There are no other transformations of the graph.

Which of these equations shifts a radical equation right 5 times and down once?
