Question

Does the equation represent a linear or nonlinear function?

y=x2+3

Answer 1

Answer: Nonlinear function.

Explanation:

the variables do not have powers more than 1,

variables do not occur in the denominator of a fraction.

different variables do not appear in the same term

In this case, there is a term in x2

so the function is not linear.

It is a parabola.

Answer 2

Nonlinear function.

Explanation:

If the x2 is supposed to mean x², then the function is quadratic, not linear.
