Replace x with each value then solve:
f(3) = 2(3) +1 = 7
f(0) = 2(0) +1 = 1
f(2) = 2(2) +1 = 5
f(1) = 2(1) + 1 = 3
Now you have:
7 -1 / 5 -3 = 6/2 = 3

Answer:
8 and 2
Step-by-step explanation:
Let x = the smaller number.
Let y = the larger number.
Let the numbers be x and y
x+y = 10 ..............(1)
y= 4x ........(2)
Put value of y into equation 1
x + y = 10
4x + x = 10
5x = 10
Divide both sides by 5
x = 10/5 = 2
Put value of y into equation 2
y= 4x
y= 4(2)
y = 8
Therefore the numbers are 8 and 2
