Student a and student b were given the following graph and asked to find the value of f(x) when x = 1. student a gave an answer of 0 while student b gave an answer of −2. who is incorrect?

probably .5

i can on others if necessary.

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)

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
