Question

A function f(x) is shown below.

f(x) = x + x + x

Write an equivalent form of f(x) in function notation that contains only one term on the right side of the equation.

Answer 1

It would be 0 because 0=3x and 3x=0 so the answer would be x=0

Answer 2

f(x) = 3x

Explanation:

when adding x (the same variable) to eachother when there is nothing in front, you always assume the coefficient is 1. since there are 3 x's, (1)x+(1)x+(1)x=3x. hope this helps:)
