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.

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.
