Intro to Radical Function Graphs (U5L1)

What is a radical?

• a root symbol

• an equal sign

• a division symbol

• the answer is imaginary (because you can't do the square root of a negative)

Where is the y going on the right end?

How do we know the center is at (1,5)?

• it is where the graph switches concavity (straight up and down point)

• it is the middle of the graph (0,0)

• it is always where the graph is concave up

• it is always where the graph is concave down

What is the domain?

• x values

• y values
