Please Help

Answer 1

A.

Answer 2

B.

Answer 3

C.

Answer 4

D. f(x) = –4x

Answer 5

The first function is quadratic because of the x^2 term. It is a parabola.

The second term can be simplified to: 2x + 1/2 which is linear (because there is an x in the denominator we have to mention the function is not defined for x = 0 but it is a straight line for all other x values).

The third and fourth are linear because of the x term and so they are all straight lines except the quadratic.
