Front

What is the square root of 81?

Back

9

Front

What does it mean for a function to be shifted left by 2 units?

Back

The entire graph of the function moves 2 units to the left on the x-axis.

Front

What is the equation of the graph if it is transformed from the parent function y = √x?

Back

y = √(x - 5) + 4 represents a shift right by 5 and up by 4.

Front

What is the range of the function y = √(x - 5) + 4?

Back

y ≥ 4.

Front

Back

3/5.

Front

What is the parent function of a square root function?

Back

y = √x.

Front

How do you determine the range of a square root function?

Back

The range is determined by the minimum value of the function, which is the y-value when x is at its minimum.

Front

What does it mean for a function to be transformed up by 2 units?

Back

The entire graph of the function moves 2 units up on the y-axis.

Front

What is the effect of a negative sign in front of a square root function?

Back

It reflects the graph across the x-axis.

Front

What is the domain of the function y = √(x - 3)?

Back

x ≥ 3.
