Answer:
Mark's mass is 26 kg.
Step-by-step explanation:
Average mass of Jeremy, Mark and Zack = 28kg
Average mass of Jeremy and Zack = 29 kg
Let,
Jeremy's mass = x
Mark's mass = y
Zack's mass = z
Average of three of them = 
28 = 

x+y+z = 84 Eqn 1

x+z = 58 Eqn 2
Now putting value of x+z from Eqn 2 in Eqn 1
x + z + y = 84
58 + y = 84
y = 84 - 58
y = 26
Thereofore,
Mark's mass is 26 kg.
To determine if the given points are on the graph of the function, substitute the x- coordinate into the equation and if the value is equal to the y-coordinate then it is on the graph
(0, - 16 ) : f(0) = 0 + 1 = 1 ≠ - 16 → No
(- 1, - 1) : f(-1) = 16 + 1 = 17 ≠ - 1 → No
(1, 256 ) : f(1) = - 16 + 1 = - 15 ≠ 256 → No
You would need 2 & 1/2 because if for 3 you need 1 & 1/2 ( which is half) then for 5 you would divide it by 2 and get 2 & 1/2
