Learn how to graph an absolute value function with a vertical shift

The video tutorial covers four basic functions: identity, constant, absolute value, and quadratic. It explains how to graph absolute value functions using a table of values and describes the concept of absolute value as the distance from zero. The tutorial also discusses how transformations, such as adding or subtracting, affect the graph's position.

Which of the following functions is represented by a diagonal line on a graph?

• Quadratic function

• Identity function

• Absolute value function

• Constant function

What shape does the graph of an absolute value function typically have?

• U-shape

• V-shape

• S-shape

• L-shape

When graphing an absolute value function, what is the first step you should take?

• Determine the slope

• Graph the parent function

• Identify the x-intercepts

• Calculate the y-intercepts

If you subtract a number outside of a function, how does it affect the graph?

• Shifts the graph down

• Shifts the graph to the right

• Shifts the graph to the left

• Shifts the graph up

What happens to the graph if you add a positive number inside the function?

• The graph shifts down

• The graph shifts up

• The graph shifts to the right

• The graph shifts to the left
