Geometry

posted by on .

using the 8 steps in Sec 4.3 of your book, analyze the graph of the following function.
R(x)= x^2+x-30/ x^2-x-20

  • Geometry - ,

    Without knowing the 8 steps to which you are referring, you can do the following:
    Factor both numerator and denominator:
    R(x)=(x-5)(x+6)/[(x-5)(x+4)]
    You will find the zeroes and asymptotes.
    Since there is a common factor (x-5), the point f(5) is indeterminate and should be taken out of the domain.
    Check against your eight steps.
    If it's not clear, please post which step you need further explanations.
