B. y = x² - 3x + 2.25
This function is not linear because it includes a term with x raised to the power of 2 (x²), which makes it a quadratic function. Linear functions have variables raised only to the first power.
Which of the following gives an example of a function that is not linear? (1 point)
A. 9x + 3y - 18 = 0
B. y = x² - 3x + 2.25
C. 2x + 3y = 16
D. y = 1/6x + 2/3
