2.1 Intro to Functions

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain.

Remember: Domain is x

(x,y)

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{-4, 0, 1, 2}

  R:{-4, -3, 1}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

Which graph does NOT pass the vertical line test?

• Graph 1
• Graph 2
• Graph 3
• Graph 4

What is the range of the following relation:
(9, -2) (4, 3)  ( 8, 10) ( -4, 8)
Range is the y values 
(x,y)

• -4, 4, 8, 9
• -2, 3, 8, 10
• (9, -2) ( 4, 3)
• (8, 10) (-4, 8)

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D: {-4, 0, 1, 2}

  R:{-4, -3, 1}

• D: {0, 1, 2, 3, 4}

  R:{1, -3, -4}

Evaluate f(t)=-2t²+ 1 for f(-3)

Hint: Type in x instead of t

• 19

• 37

• -17

• -11

g(x) = 5 - 6x
Find g(-5)

• g(-5) = -25
• g(-5) = 6
• g(-5) = 4
• g(-5) = 35
