Answer:
The common continuous interval will be (0,∞).
Explanation:
Given that,
The numerator = 12+√x
The denominator = √12+x
We know that,
For the numerator,
Any function under square root should be greater than and equal to the zero.

So, the continuous interval is (0, ∞)
For the denominator,



The interval for the continuous and non zero function is,
(-12, ∞)
We need to calculate the continuous interval
Using given quotient

The continuous interval of numerator and denominator are (0, ∞) and (-12, ∞).
Hence, The common continuous interval will be (0,∞).
