Answer:
The domain of function is set of all real numbers.
Domain: (-∞,∞)
Step-by-step explanation:
Given:
the domain of both the above functions is all real number.
To find domain of :
Substituting functions and
to find
The product can be written as difference of squares.
∴
The degree of the function is 2 as the exponent of leading term
is 2. Thus its a quadratic equation.
For any quadratic equation the domain is set of all real numbers.
So Domain of is (-∞,∞)
Answer:
A
Step-by-step explanation:
We are given the function:
And we want to find:
So, we need to determine whether or not the limit exists. In other words, we will find the two one-sided limits.
Left-Hand Limit:
Since we are approaching from the left, we will use the first equation:
By direct substitution:
Right-Hand Limit:
Since we are approaching from the right, we will use the second equation:
Direct substitution:
So, we can see that:
Since both the left- and right-hand limits exist and equal the same thing, we can conclude that:
Our answer is A.
