Find the domain of the following set:
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
D: {-5, -1, 0, 2}
Identify the domain and range of the following:
D: (-2,4)
R: [-3,3]
Does the following represent a function? Why or why not?
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
No, -1 has two different outputs.
f(x) = 3x + 4
Find f(2).
f(2) = 10
Find the range of the following set:
{(2, 1) (-1, 0) (-1, 3) (0, 2) (-5, 1)}
R:{0, 1, 2, 3}
What is the domain and range of the graph?
Domain: [0, infinity)
Range: [-2, infinity)
Does the following represent a function? Why or why not?
No because -2 goes to both 1 and 3.
What is f(5)?
f(5) = 4
Find the domain and range of the following:
{(0, 1) (0, 2) (0, 0) (0, -2) (0, -8)}
D: {0}
R: {-8, -2, 0, 1, 2}
What is the domain and range of the following?
Domain: All real numbers
Range: [-4, infinity)
Is the following a function?
No, it doesn't pass the vertical line test.
g(x) = x2 -3x + 4
What is g(3)?
g(3) = 4
What is the domain of the following?
{2, 3, 5, 7, 9}
What the domain and range of the following?
D: [-2 , 6] R: [-6 , 2]
Is the following a function?
No, it doesn't pass the vertical line test.
f(x) = 4|x| - 6
g(x) = -2x +7
What is f(-3) - g(1)?
f(-3) - g(1) = 1
Draw a graph with a range of [2,5] and a domain of
(-oo,oo)
Multiple answers
Identify the domain and range of the following graph.
Range: {2}
Domain: All real numbers
Is the following a function? Why or why not?
Yes. Every input has only one output. The holes in the graph make it so that no x values will repeat.
g(x) = 0.5x - 4
What is g(2y - 4)?
g(2y - 4) = y - 6
