Question

Which equation represents a nonlinear function?
x=-3
y=2
y=-2(x-5)
y=x(3x+1)

Answer 1

y=x(3x+1)

Explanation:

A nonlinear function is every function whose graph is not a line.

Y=x(3x+1) is a quadratic function, so it's graph is a parabola, not a line.

Hope this helps!

Answer 2

y = x(3x + 1) is not linear

Explanation:

This equation is not linear because it will have an
`x^(2)` which is not linear

y = x(3x + 1)

y = 3
`x^(2)` + x
