So, we have:
Rewrite as:
Hence, the new function is:

Which of the following describes the function −x3 + 5?
1 answer:
Answer:
The correct choice is C
Step-by-step explanation:
The given function is:
The degree of this function is odd so the function will rise at one end and fall on the other end.
Since the coefficient of the leading term is negative, the graph of the function will rise at the left and fall on the right.
The correct answer is option C.

Answer:
3 times more.
Step-by-step explanation:
The odds of landing a dart in any of the circles correspond to the surface area of the circle.
Calculate the surface area of both circles:
The formula for the area of a circle is .
- inner circle:
- for the outer circle, use the formula then subtract the value of the inner circle, to find the remaining area:
Calculating greater chance:
Divide the larger area by the smaller area:
That means that the area of the outer circle is 3 times larger, making it 3 times more likely to hit the outer circle. Therefore the points for hitting the inner circle should be 3 times more.
