Absolute Value Graphs

Front

What is the equation of the absolute value function?

Back

f(x) = |x| + 4

Front

Which graph represents the parent function of an Absolute Value?

Back

The blue graph represents the parent function f(x) = |x|.

Front

What is the vertex of the absolute value function?

Back

The vertex is (0, 4).

Front

y = |x - 3| makes the graph slide . . .

Back

right 3

Front

If the blue graph is the parent function f(x) = |x|, what is the red graph?

Back

g(x) = |x - 2|

Front

What does the absolute value function represent?

Back

The distance of a number from zero on the number line.

Front

How does the graph of f(x) = |x| + k differ from f(x) = |x|?

Back

It shifts the graph vertically by k units.

Front

What effect does the negative sign have in f(x) = -|x|?

Back

It reflects the graph across the x-axis.

Front

What is the domain of the absolute value function f(x) = |x|?

Back

The domain is all real numbers, (-∞, ∞).

Front

What is the range of the absolute value function f(x) = |x|?

Back

The range is [0, ∞).
