Question

If the function 5x+y=1 has the domain (-2, 1, 6), then what is the corresponding range?

Answer 1

Domain (x-values)

Range (y-values)

Since they gave you the domain/x-values = -2, 1, 6, you can find the corresponding range/y-values by plugging in these values for "x" in the function:

x = -2

5x + y = 1    Substitute/plug in -2 into "x" to find the value of y

5(-2) + y = 1

-10 + y = 1     Add 10 on both sides to get "y" by itself

y = 11

x = 1

5x + y = 1    Plug in 1 into "x"

5(1) + y = 1      Subtract 5 on both sides

y = -4

x = 6

5x + y = 1

y = -29

Your answer is D
