Graphing Radical Functions Quiz

What is the parent graph for radical functions?

• y = √x

• y = x^2

• y = 1/x

• y = x^3

If a radical function has no number in front of the radical, what is the value of 'a'?

• 0

• 3

• 2

• 1

How does a negative sign outside the radical affect the graph?

• Reflects over the x-axis

• Reflects over the y-axis

• Shifts down

• Shifts up

In interval notation, how is the domain of a function that starts at x = -3 and extends to positive infinity expressed?

• (-∞, -3]

• [-3, ∞]

• [-3, ∞)

• (-3, ∞)

Why is a table useful when graphing a radical function with an 'A' value?

• It simplifies finding perfect squares under the radical

• It determines the slope

• It helps identify the y-intercept

• It finds the x-intercept

What is the first step in using a table to graph a radical function?

• Choose random x-values

• Select x-values that result in perfect squares under the radical

• Find the slope

• Start with the y-intercept

How does a negative sign inside the radical affect the graph?

• Shifts right

• Reflects over the y-axis

• Shifts left

• Reflects over the x-axis

What is the spatial relationship between points on the parent graph y = √x?

• Over 3, up 3

• Over 2, up 2

• Over 5, up 5

• Over 1, up 1; Over 4, up 2

What is the domain of a function that reflects over the y-axis and starts at x = -2?

• (-∞, -2]

• [-2, ∞)

• (-2, ∞)

• [-2, ∞]

In interval notation, how is the range of a function that starts at y = 1 and extends to positive infinity expressed?

• [1, ∞)

• (1, ∞)

• (-∞, 1]

• (-∞, 1)
