Identify the function below as S for step, C for constant, A for absolute value, I for identity, or P for piecewise.
Answers (C, A, B, A The graph of a step function is not linear. When the graph is a horizontal line, it is a constant function. The absolute value function is f(x) = | x |. A function written using two or more expressions is called a piecewise function.)
