Given the range of the function, find the corresponding domain. f (x) = 4x - 1 Range: {3, 7, 11, 15}

The range is the output value or the y value.

You would work backwards to find the domain.

f (x) = 4x - 1 f (x) = 4x - 1

3 = 4x - 1 7 = 4x - 1

add 1 to both sides add 1 to both sides

4 = 4x 8 = 4x

divide both sides by 4 divide both sides by 4

x = 1 x = 2

f (x) = 4x - 1 f (x) = 4x - 1

11 = 4x - 1 15 = 4x - 1

add 1 to both sides add 1 to both sides

12 = 4x 16 = 4x

divide both sides by 4 divide both sides by 4

x = 3 x = 4

Domain { 1, 2, 3, 4}
