CCSS.HSF.IF.B.5

The following is not a function because...

• There are two values that equal 2.

• x = 10 and x = 40 has two values each.

• In the f(x) column, the 5 repeats.

• This table is actually a function.

What is the range?

• <-3, -1, 2, 4>

• <0, 4, 7> 

• <0, 4, 4, 7>

• <7, 4, 0>

Answer explanation

The range is the set of values that a function can take. The correct choice {0, 4, 7} includes all possible outputs, while the other options do not represent a complete range of values.

CCSS.HSF.IF.A.1

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}

• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}

Answer explanation

The domain consists of the first elements of the pairs: {-4, 0, 1, 2}. The range consists of the second elements: {-4, -3, 1}. Thus, the correct choice is D: {-4, 0, 1, 2} and R: {-4, -3, 1}.
