Answer:
The answer to your question is 0 < x ≤ 3
Step-by-step explanation:
To write this inequality we must consider
- The value of the borders, for this inequality the borders are 0 and 3.
-The kind of border - if it is an open point, we will use the symbol <
- if it is a close c point, we will use the symbol ≤
-The inequality for this problem will be
0 < x ≤ 3
Answer:
f is not defined at x = 3 ⇒ answer (b)
Step-by-step explanation:
∵ f(x) = x² - x - 6/x² - 9 is a rational function
∴ It will be undefined at the values of x of the denominator
∵ The denominator is x² - 9
∵ x² - 9 = 0 ⇒ x² = 9 ⇒ x = ±√9
∴ x = ± 3
∴ f(x) can not be defined at x = 3
∴ The f(x) can not be continuous at x = 3
∴ The answer is (b)
