Question

Which two equations represent a nonlinear function?

y=2(x−1)+1

y = 2 ( x − − 1 ) + 1

y=2x−1

y = 2 x − − 1

y=(x−1)2

y = ( x − − 1 ) 2

y=x−1

y = x − − 1

y=3x−1

y = 3 x − − 1

Answer 1

Answer: See below.

Explanation:

The formatting is likely incorrect for these two options:

y=(x−1)2, and

y = ( x − − 1 ) 2

I'll assume they were meant to be:

y=(x−1)^2, and

y = ( x + 1 )^2

In this case they would be non-linear, since y depends on the value of
`x^(2)`

Use a "^" sign to indicate raised to a power: x^2 means
`x^(2)`.

y=(x−1)2 means y = 2x - 2

y=(x−1)^2 means y =
`(x-1)^(2)`
