Question

describe how you can tell by lookin at a graph of a function which variable is the input variable and which is the output variable

Answer 1

The output variable will be on the y-axis, the input variable will be on the x-axis.

Explanation:

To create a function, we must an equation in the form of

`Y(x) = kx + b`

The x-axis of a graph will be what we change in the function. We will get a certain value (
`Y(x)`) that changes when the right side of the function changes. This means that the input of the function will be
`x`.

The y-axis of a graph will be what the x-axis makes. In this case, it's
`Y(x)`. This is the output of the graph after given the input. This means the output is
`Y(x)`.

Hope this helped!
