Answer:
B.
Step-by-step explanation:
(21, 7)
because the x axis is the number of minutes and the y axis is the x axis divided by 3
let the number be x
According to above statement :
p(4)= 8
p(-9)=-5
it is stated in the third point that the remainder of the division is zero
then p(x)/(x+4)=1
p(x)=(x+4)
p(4)=(4+4)
p(-9)=(-9+4)
