Understanding Radical Functions and Their Transformations

Miss Smith's tutorial explains how to write radical functions from graphs. It covers identifying reflections over the x and y axes, determining endpoints, and writing equations. The video includes examples of standard radicals, reflections over the x-axis, y-axis, and both axes.

What is the main topic discussed in the video?

• Writing radical functions from a graph

• Understanding logarithmic functions

• Graphing linear equations

• Solving quadratic equations

What does a positive sign in a radical function indicate?

• The function is shifted vertically

• The function is flipped over the y-axis

• The function is in its standard form

• The function is flipped over the x-axis

How does a negative sign affect a radical function?

• It reflects the function over the x-axis

• It stretches the function vertically

• It reflects the function over the y-axis

• It shifts the function horizontally

What is the first step in determining the equation of a radical function from a graph?

• Determine the slope

• Identify the y-intercept

• Calculate the area under the curve

• Find the endpoint

In Example 1, what is the endpoint of the graph?

• (1, 2)

• (0, 0)

• (3, 4)

• (-1, -1)

In Example 2, how is the graph reflected?

• Over the x-axis

• Over the y-axis

• Not reflected

• Over both axes

In Example 3, what is the value of 'a' in the equation?

• 1

• 3

• 2

• 4

In Example 4, what is the significance of having two negative signs?

• The function is reflected over both axes

• The function is shifted vertically

• The function is in its standard form

• The function is stretched horizontally

What should you do if you see a negative sign inside the parentheses of a radical function?

• Shift the function vertically

• Reflect the function over the y-axis

• Reflect the function over the x-axis

• Ignore it
