Use the piecewise-defined function to find the following values for f(x). 4- 2x f(x) = if 27 f(-3)= f(2)=( f(4)= f(6)=0 f(7)=

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )
