4. The degree of a function is the largest exponent of x in the equation. A linear function, such as y = 2x 1 - 3, has a degree of ____. A quadratic function, such as y = -2x 2 + 4, has a degree of ____. If a function has any other degree it is neither linear nor quadratic. eg y = 3x 3 -2x + 5

6. If the first differences are all the same, the function is linear. If the second differences are all the same, the function is quadratic.

7. Determine if each of the following functions are linear, quadratic, or neither. a) y = -4x 4 + 3x 2 - 6 b) y = x(x + 4) c) y = x 2 + 2x - (x 2 - 3)
