Quarter2 Independent Assignment #7 on Solving Radical Equations

Front

What is the parent function of a square root?

Back

The parent function of a square root is y = √x.

Front

What is the first step to solve the equation -3 = √(x - 4) + 8?

Back

Subtract 8 from both sides to isolate the radical.

Front

What effect does the equation y = √(x + 3) have on the graph of the parent function?

Back

It shifts the graph of the parent function left by 3 units.

Front

What is the solution to the equation √(x) = 6?

Back

x = 36.

Front

What does the -3 in the equation y = √[3]{x - 3} + 2 do to the graph?

Back

It moves the graph to the right by 3 units.

Front

What is the domain of the function y = √(x - 4)?

Back

The domain is x ≥ 4.

Front

How do you solve the equation √(x + 2) = 4?

Back

Square both sides to get x + 2 = 16, then solve for x.

Front

What is the range of the function y = √(x)?

Back

The range is y ≥ 0.

Front

What is the solution to the equation √(x - 1) = 3?

Back

x = 10.

Front

What does the equation y = -√(x) represent?

Back

It reflects the graph of the parent function y = √(x) across the x-axis.
