Answer:
3.3 :)
Step-by-step explanation:
Answer: Option B
2 is NOT in the domain of f ° g
Step-by-step explanation:
First we must perform the composition of both functions:
If and not
The domain of the composite function will be all real numbers for which the term that is inside the root is greater than zero. When x equals 2, the expression within the root is less than zero
The root of -7 does not exist in real numbers, therefore 2 does not belong to the domain of f ° g
The answer is Option B.
<em>Note. If </em>
So
And 2 belongs to the domain of the function
Answer:
{-3, 8}
Step-by-step explanation:
This rational expression is undefined wherever the denominator is 0.
Thus, our task is to determine the roots of x² - 5x - 24:
This expression factors as follows: (x - 8)(x + 3) = 0
Setting x - 8 = 0 and solving for x yields x = 8.
Similarly, x + 3 = 0 yields x = -3.
This rational expression is undefined for {-3, 8}.
