All Functions of Integers

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.

Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)

• (3,4) (4,-3) (7,4) (3, 8)

• (6,-5) (7, -3) (8, -1) (9, 1)

• (2, -2) (5, 9) (5, -7) (1, 4)

Is it a function?

• Yes

• No

What is the domain?

• {-2, -1, 0, 1, 8}

• {3, 5, 7 , 9, 0}

• {-2, -1, 0, 1, 3, 5, 7, 8, 9}

• {-2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Before a bowler rolls her first ball, 10 pins are standing. The number of pins that will be left standing, y, is a function of the number of pins she knocks down. What is the domain of this function?

• { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

• { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

• y ≤ 10, integers

• 0 ≤ y ≤ 10, real numbers

What is the range of the following graph?

• {-5, -1, 0 , 1, 5}

• {-4, -2, 0, 3, 6}

• {-4, 0, 1, 6}

• {0, 6}

Find the function rule.

• y = 2x

• y = 2x+3

• y = 3x+3

• y = 2x+3
