Question

Please help!!! I’m so bad at math.

Answer 1

Answer:

x = - 9 , 6

Step-by-step explanation:

The given function is  

$h(x) = \frac{x - 8}{x^{2} + 3x - 54}$

⇒ $h(x) = \frac{x - 8}{(x - 6)(x + 9)}$

Therefore, the value of h(x) will be undefined for the denominator equal to zero.

So, (x + 9)(x - 6) = 0

⇒ x = - 9 and x = 6

Therefore, the values of x which are not in domain of function h(x) are x = - 9 , 6. (Answer)
