Answer:
- domain (-∞, ∞)
- range (-∞, 4]
- increasing (-∞, 0)
- decreasing (0, ∞)
- constant (only at x=0, not on any interval)
Step-by-step explanation:
The graph is of the equation y = -x^2 +4. It is a polynomial of even degree, so has a domain of all real numbers: (-∞, ∞).
The vertical extent of the graph includes y=4 and all numbers less than that:
range: (-∞, 4]
The graph is increasing to the left of its vertex at x=0, decreasing to the right.
increasing (-∞, 0); decreasing (0, ∞)
There is no interval on which the function is constant. It has a horizontal tangent at x=0, but a single point does not constitute an interval.
Answer:
I got 235, which works in perfectly into the problem...
Step-by-step explanation:
5:12 means there are 17 parts
Percentages are calculated by dividing the part by the total, and multiplying by 100
Julie put in 5 out of 17 parts so:

×100=29.4%
Kristen owns the rest of the business

×100=70.6%
The amount of money doesn't make a difference, as the percentage will always be the same.
