Question

Write the following linear equation in function notation. y = 2x + 5?

Answer 1

`f(x)=2x+5`

Explanation:

Function notation is a system of representing functions.

Functions are special types of relations. If a relation produces exactly one output (`y`) for each input (`x`), then it is called a function.

You can write a relation in function notation by replacing `y` with `f(x)`. This is pronounced "f of x", and means "the value of the function given the input `x`.
