find the domain of function

f(x)= (5x + 4)/(x^2 + 3x + 2)

is the answer..
x can't be -2 or -1?

  • calculus -

    how do you properly write the answer?

  • calculus -

    yes, x must not be equal to -2 and -1

    (-00,-2)U(-2,-1)U(-1,+00)

    *00==>infinity symbol (it should look like an 8 rotated 90 degrees clockwise..)
    *U==>union

    i hope i was able to help you.. =)
