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

• All integers

• All non-negative real numbers

• All real numbers

• All positive real numbers

When graphing g(x) = |x + 2|, why is it important to include negative x-values?

• To ensure the graph is a straight line

• To avoid errors in calculations

• To make the graph symmetrical

• To get a full understanding of the V shape

Why do we need to continue plotting points for g(x) = |x - 4| until we see the V shape?

• To avoid errors in calculations

• To capture the repeating pattern of values

• To confirm the graph is symmetrical

• To ensure the graph is a straight line
