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.

    Thanks.
