f(x)=v^2+13/v^2-4v-32
Find all numbers that are not in the domain of the function. Then give the domain in set notation.

  • algebra -

    set denominator equal to 0 and solve for x which would make the equation undefined
    v^2-4v-32=0
    (v-8)(v+4)=0
    v=8, v=-4
    x is not equal to 8 or -4

  • algebra -

    The denominator cannot be zero, so find the roots of the denominator.

    (v-8)*(v+4)=0
    so v cannot be 8, or -4
