Let f(x)=x−[x] where [x] denotes the greatest integer that is less or equal to x.

the probability is 0

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
