consider the function in the graph to the right. the function has a select an answer of at x = the function is increasing on the interval(s): the function is decreasing on the interval(s): the domain of the function is: the range of the function is: question help: video submit question
Answer
Answer:
- The function has a maximum of 6.25 at $x=-3.5$.
- The function is increasing on the interval(s): $(-\infty, - 3.5)$.
- The function is decreasing on the interval(s): $(-3.5,\infty)$.
- The domain of the function is: $(-\infty,\infty)$.
- The range of the function is: $(-\infty,6.25]$.
Explanation:
Step1: Identify the vertex
The highest - point of the parabola is at $(-3.5,6.25)$, so it's a maximum.
Step2: Determine increasing interval
The function rises from negative infinity to $x = - 3.5$.
Step3: Determine decreasing interval
The function falls from $x=-3.5$ to positive infinity.
Step4: Find the domain
Since the graph extends horizontally without bound, domain is all real numbers.
Step5: Find the range
The maximum value is $y = 6.25$ and the function goes downwards, so range is $y\leq6.25$.
