Intro to Functions/Linear Functions

What is the definition of function?

• Has inputs and outputs

• Every input has only ONE output (x Doesn't Repeat)

• Inputs have different outputs every time

• x-values and y-values

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
