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.
