The function h is is defined below.
h(x)=48x^2+ 12x - 16

Find all values of x that are NOT in the domain of h.

If there is more than one value, separate them with commas.

I'm lost.

  • Algebra restate problem - ,

    The function h is is defined below
    h(x)=(x+6)/(x^2+9x+8)

    Find all values of x that are NOT in the domain of h.

    If there is more than one value, separate them with commas.

    This is a rational function.
    The domain is in the Real numbers, i.e. (-∞,∞) except where the denominator becomes zero.
    Therefore solving for
    (x^2+9x+8) = 0
    (x+8)(x+1) = 0
    or x=-8, or x=-1.
    Therefore the values of x that do not belong to the domain of f(x) is -8 and -1.
