Answer:
Your in middle school you should know this figure this by now FIGURE IT OUT ON YOUR OWN.....
Step-by-step explanation: yeah
Answer:
third option: (x+3) / √x+2
Step-by-step explanation:
f(x) = √x+2 g(x) = (x² + 1) / x
(g·f)(x) = g(f(x)) = ((√x+2)² + 1) / √x+2
==> (x+2+1) / √x+2
==> (x+3) / √x+2
1. If x = -2, then
y = (-2)^2 - 2(-2) - 1
= 4 + 4 - 1
= 7
2. If x = 0, then
y = (0)^2 - 2(0) - 1
= 0 - 0 - 1
= -1
3. If x = 2, then
y = (2)^2 - 2(2) - 1
= 4 - 4 - 1
= -1
4. If x = 3, then
y = (3)^2 - 2(3) - 1
= 9 - 6 - 1
= 2
Hope you could understand.

Step-by-step explanation:
Answer:
a) 4.33 (three repeating)
b) 3.5
c) 3
d) 0.44
Step-by-step explanation: Mean is all the numbers added up and divided by the amount of items. All the items added together are 78. We have 18 items 78/18 = 4.3 (three repeating). Median is just the middle value. This is between 3 and 4 so 3.5. Mode is the one that shows the most. This is 3. 8 students play games for more than 4 hours. 8/18 = 0.44
