Question

Is the function linear or nonlinear y=2x^2-4

Answer 1

The function is nonlinear.

Answer 2

ANSWER


The function is non linear.

Step-by-step explanation

A linear function is of the form


`y = mx + c`


or


`ax + by + c = 0`


The highest degree of the variables in each term in the simplest form is 1.


Any degree higher or less than 1 will make the function nonlinear.


The function given to us is,


`y = 2{x}^(2) - 4`

The highest degree is 2. This is a quadratic curve.


The graph of all linear functions are straight lines.
