Your second equation has 2 x-intercepts because its curve goes beneath the x-axis, meaning it crosses the x-axis twice. Your first equation has only one x intercept because its vertex touches the x-axis. The transformation that occurred was a vertical shift downwards, (since the image function has that little -7 at the end : ) )
Answer:
Where are the questions....?
Answer: Third option.
Step-by-step explanation:
By definition, Rational Functions have the following form:
Where and are polynomials.
The Restrictions of the Domain of Rational Functions are those Real numbers that make the denominator equal to zero, because the division by zero is not defined.
In this case, you have the following Rational Function:
The Restrictions of the Domain can be found applying this steps:
- Make the denominator equal to 0:
- Solve for "x":
Then, the Domain of this function includes all "x" not equal to 2.
Therefore, the answer is:
