In a math contest, the contestants were given the following piecewise graph. For the final question, they were asked to write the piecewise function of the graph. Circle the name of the competitor with the correct answer.
(Sorry the names aren't in the pictures just find the right function)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
