1. 3!/5! = 3*2 / 5*4*3*2 = 6/120 = 1/20

2. 5! / 8! = 5*4*3*2 / 8*7*6*5*4*3*2 = 120 / 40320 = 1/336

3. 9!/9! = 1

4. 7! / 8! = 7*6*5*4*3*2 / 8*7*6*5*4*3*2 = 5040 / 40320 = 1/8

5. 5! / 7! = 5*4*3*2 / 7*6*5*4*3*2 = 120 / 5040 = 1/42

Please help me: What's the domain? What's the range? Is it a function?

VladimirAG [237]

Answer:

$\displaystyle Yes \\ Range: Set-Builder\:Notation → [f(x)|-2 ≤ f(x) ≤ 4] \\ Interval\:Notation → [-2, 4] \\ \\ Domain: Set-Builder\:Notation → [x|0 ≤ x ≤ 7] \\ Interval\:Notation → [0, 7]$

Step-by-step explanation:

Just by looking at the graph vertically and horisontally, you can tell what the range and domain is, depending on whether the segments are closed or opened.

* This is a function because it passes the vertical line test.

** This is kind of like a sine wave.

I am joyous to assist you anytime.
