Evaluating Functions

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values paired 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 paired with it.

• No, because each x-value has only one y-value paired with it.

Is this graph a function or not a function? 

• Function

• Not a Function

Is the following graph a function? Explain.

• Yes, because no x-value repeats.

• Yes, because they are individual dots.

• No, because the x repeats.

• No, because it is not a line.

How would you write y = 2x - 3 in function notation?

• y = 2x-3

• f = 2x - 3

• f(x) = 2x - 3

• Can't be written in function notation
