Question

Justus samples 3 oranges from each of his trees ,plus an extra 50 oranges from the whole orchard , to judge whether it is time to harvest. Write a function rule for the number of oranges Justus samples.Use x for the independent variable and y for the dependent variable. Type your answer in standard function notation, like this: f(x)=14x-42

Answer 1

let there are x number of trees

Justus samples 3 oranges from one tree

Number of oranges he samples from x trees =3x

Extra oranges =50

total number of oranges = 3x+50

as a function f(x) we can write it as

f(x) =3x+50

Answer 2

let there are x number of trees

Justus samples 3 oranges from one tree

Number of oranges he samples from x trees =3x

Extra oranges =50

total number of oranges = 3x+50

as a function f(x) we can write it as

f(x) =3x+50
