Question

Does y = x2 + 1 represent a linear or nonlinear function? Explain.

Answer 1

Answer: the function is nonlinear

Explanation:

y = x2 + 1 is a nonlinear equation because for it to be an linear question it must be the following

Linear:

2x-1=y

y=2x-1

nonlinear

y = x2 + 1

• Linear equations are a constant slope ( straight line ) and nonlinear equations has a slope that varies between points so y = x2 + 1 is an non-linear equation because it has an slope that varies between points.
