1. Write the domain of the function given in the graph in set builder notation.
A) (x|x >= 10) Is it A?
B) (x|x >= 0)
C) (x|x > 10)
D) (x|x > 0)

2. Write the range of the function given in the graph in interval notation.
A) [4,8]
B) (-4,3)U(3,8]
C) (-4,8]
D) [-4,3)U(3,8) Is it D?

Answer 1

The first one would be A and the second one C

Answer 2

Using domain and range concepts, the correct options are:

• A) (x|x >= 10)

• C) (-4,8]

-----------

• The domain of a function are the input values, that is, the values on the x-axis.
• The range of a function are the output values, that is, the values on the y-axis.

-----------

• On the first graph, we want to find the domain.
• x assumes values starting at 10, and going to infinity. Thus the domain is: (x|x >= 10), option A.

-----------

• On the second graph, we want to find the range.
• y assumes values from -4, exclusive due to the open circle, to 8, inclusive due to the closed circle.
• 3 is part of the range, due to the closed circle at x = -3.
• Thus, the correct option is: C) (-4,8]
