Graph the function f(x) = x3 – 10x2 + 28x – 24 Then, write a
katovenus [111]

- Cubic Function | 3-degree

- Domain & Range | Domain and Range both are all set of Real Numbers.

- End Behavior | When x approaches positive infinity, f(x) approaches positive infinity as well. When x approaches negative infinity, f(x) approaches negative infinity too.

- Intervals of Increasing/Decreasing | Increases at (-∞, 2) U (6,∞) and Decreases at (2,14/3) aka 2 < x < 14/3

- Intervals of Positive/Negative

Positive when x > 6 or (6,+∞)

Negative when 2 < x < 6 and x < 2 or (2,6) U (-∞,2)

- Turning Points are (2,0) and (14/3, -256/27)

- Zeros and Multiplicity | Factoring the polynomial as we get (x-2)(x-2)(x-6). Therefore, the zeros are multiplication of 2 and 6.

Multiplicity will affect the graph for x-axis. When the multiplicity kicks in, the graph will turn either decreasing on increasing on x-axis immediately.

an amusement park charges 5$ for admission and 2$ for each ride write an expression for the total cost of admission and r rides
jeyben [28]
C = 5 + 2r

You can go on 5 rides.



First, create the expression for the cost.

c = ?



Since the price of admission is $5, that becomes a term in the expression, so the new expression is:

c = 5 + ?



And since you need to pay for each ride (r) that also becomes a factor in the expression. Giving you:

c = 5 + 2r + ?



There isn't anything else that costs you money, so you can get rid of the placeholder of + ? giving you a final expression of

c = 5 + 2r



Now you need to figure out how many rides you can go on for $16. Lets figure it out.



You first have to subtract the price of admission. So you get

16 - 5 = 11



So after being admitted, you now have $11 in which to pay for rides. Since each ride costs $2, simply divide 11 by 2.

11 / 2 = 5.5



Since you really can't go on half a ride, that means you can go on 5 rides after being admitted to the park.

Answer:

The range would be increased by 2

3,5,5,5,6

The range for that set would be 3.

If 8 were added... 3,5,5,5,6,8

The range for that set would be 5.
