Identify Domain and Range and Function Exit Ticket

Is the relation shown a function?

• No, because the x-value 11 is paired with 5 and 8.

• Yes, because each x-value has only one y-value paired with it.

Find the Range.

• (-∞, +∞)

• (0, 11)

• [0, ∞)

• (0, ∞)

What is the domain?

• x = 2

• −∞ < x < ∞

• y = 2

• none of these

Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT a function! 

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

Which graph does NOT pass the vertical line test?

• Graph 1

• Graph 2

• Graph 3

• Graph 4

Find the Domain.

• (-∞, +∞)

• (0, 11)

• [0, ∞)

• (0, ∞)

What is the Domain of this linear function?

• [-6, 6]

• [0, 7]

• [2, 7]

• No Solution

What is the domain of a polynomial function?

• It depends on the degree of the function being even or odd.

• [0,∞)

• (-∞,∞)

• It depends on the vertex

What is the domain of the following function: ƒ(x)=√(x-10)

• (-∞,∞)

• [10,∞)

• [0,∞)

• [0,10]

• Function
• Not a Function
