Which of the following gives an example of a function that is not linear? (1 point) y=x2−3x+2.25%0D%0Ay equals x squared minus 3 x plus 2.25%0D%0A%0D%0A2x+3y=16%0D%0A2 x plus 3 y equals 16%0D%0A%0D%0A9x+3y−18=0%0D%0A9 x plus 3 y minus 18 equals 0%0D%0A%0D%0Ay=16x+23

The function that is not linear is: y = x^2 - 3x + 2.25
