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.

Step-by-step 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 = $(x-1)^{2}$
