First you'd work around the parenthesis, getting you a reduced problem of -2x-6-5.

combine like terms to receive -2x-11

now treat the f(x) as Y and you'll get y=-2x-11; toss it onto a graph and plot the individual points (your answer options)

all points except for A do not touch the line, resulting in your answer to be letter A!

hope this helps :)

What is the range of a function f(x)=-x+15 when the domain is {-3,-1,11}?
hodyreva [135]

Answer:

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}
