3. Determine whether the following table of values represents a linear, quadratic, or neither function. Show your calculations.

b) Explain how you know whether it is a linear, quadratic, or neither function.

Quadratic function

Explanation:

It is not linear because the difference between y values is not constant.

( for example) In a linear function, the difference between y values would be constant.

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
