Which of the following gives an example of a function that is not linear?(1 point) Responses 2x+3y=16 2 x plus 3 y equals 16 y=x2−3x+2.25 y equals x squared minus 3 x plus 2.25 y=1/6x+2/3 y equals Start Fraction 1 over 6 End Fraction x plus Start Fraction 2 over 3 End Fraction 9x+3y−18=0
The function that is not linear is:
y=x^2−3x+2.25
