To determine whether each function is linear or nonlinear, we need to consider their mathematical definitions. A linear function can be expressed in the form \(y = mx + b\), where \(m\) and \(b\) are constants, and it produces a straight line when graphed. In contrast, a nonlinear function cannot be expressed in this way and may produce curves, parabolas, or other forms when graphed.
Without the specific equations for Function 1 and Function 2, I can't classify them as linear or nonlinear or compare their outputs at \(x = 0\).
Please provide the equations or any additional information about Functions 1 and 2, and I can help you categorize them and answer your question about their outputs.
