Which of the following gives an example of a function that is not linear?(1 point) Responses y=x2−3x+2.25 y equals x squared minus 3 x plus 2.25 9x+3y−18=0 9 x plus 3 y minus 18 equals 0 2x+3y=16 2 x plus 3 y equals 16 y=16x+23
The example of a function that is not linear is:
y = x^2 − 3x + 2.25
This is a quadratic function, as it involves the term x^2 (x squared), which means it includes a second-degree term. Linear functions, on the other hand, only have variables raised to the first power (x), without any squares, cubes, or higher powers of variables, and they graph as straight lines. The other equations given can be simplified to the form y = mx + b (where m and b are constants), which represents a linear function.
