Did I do this right?

Find the domain and range

f(x)=-4x-2
y=-4x-2
x=-4y-2
x+2/-4=-4y/-4
f(x)=x+2/-4

answer:
domain (all real numbers)
range (all real numbers)

• Math -

Domain; 17
Range; 20

• Math -

Beth, you are correct

Since your function is a straight line with a slope of -4
the domain and range are both the set of real numbers.

• Math -

Thanks.
