Question

Identify the nonlinear equation. A) y = x B) y = 3x - 7 C) y = x2 D) y = 3 E) y = 1 3

Answer 1

ANSWER

C)

$y = {x}^{2}$

EXPLANATION

A linear function is a function whose graph is a straight line.

The graph of y=x is a straight line.

The graph of y=3x -7 is also a straight line.

The graph of y=x² is a parabola.

This graph is not a straight line .

It is a non-linear function.

y=3 and y=13 are also straight lines.

The correct choice is C.
