How to Graph Square Root Functions?

Identify the parent function: (y=sqrt{x})

Find the domain by setting the expression under the square root greater than or equal to 0

Find the starting point by setting the radicand equal to 0

Plot the starting point

Choose several x-values that make the radicand perfect squares

Calculate the corresponding y-values

Plot the points

Connect the points with a smooth curve

Apply horizontal shifts by changing (x) inside the square root

Apply vertical shifts by adding or subtracting outside the square root

Reflect across the x-axis by multiplying the square root by a negative number

Stretch or compress the graph by changing the coefficient outside the square root

Check the range based on the transformation and direction of the graph
