Evaluating Piecewise Functions

Which "piece" of the function would you use to evaluate the piecewise function for f(-4)

Evaluate the piecewise function for f(-4). Type only the number in the answer.

Evaluate the piecewise function for f(2). Type only the number in the answer.

Evaluate the piecewise function for f(8). Type only the number in the answer.

Evaluate the piecewise function for f(-2). Type only the number in the answer.

Evaluate the piecewise function for f(0). Type only the number in the answer.

Evaluate the piecewise function for f(5). Type only the number in the answer.

Evaluate the piecewise function for f(9). Type only the number in the answer.

Evaluate the piecewise function for f(3). Type only the number in the answer.

Evaluate the piecewise function for f(-4). Type only the number in the answer.
