Answer:
3
Step-by-step explanation:
Since (f/g)(x) = f(x)/g(x) for x to be in the domain of (f/g)(x) it must be in the domain of f and in the domain of g. You also need to insure that g(x) is not zero since f(x) is divided by g(x). Thus there are 3 conditions. x must be in the domain of f: f(x) = 3x -5 and all real numbers x are in the domain of x.
Given f(x) = 2x + 3 and g(x) = –x2 + 5, find ( f o f )(x).
( f o f )(x) = f ( f (x))
= f (2x + 3)
= 2( ) + 3 ... setting up to insert the input
= 2(2x + 3) + 3
= 4x + 6 + 3
= 4x + 9
Given f(x) = 2x + 3 and g(x) = –x2 + 5, find (g o g)(x).
(g o g)(x) = g(g(x))
= –( )2 + 5 ... setting up to insert the input
= –(–x2 + 5)2 + 5
= –(x4 – 10x2 + 25) + 5
= –x4 + 10x2 – 25 + 5
= –x4 + 10x2 – 20
Answer:
y≤5
Step-by-step explanation:
3 ≥ y - 2
Add 2 to both sides
3 (+2) ≥ y - 2 (+2)
5 ≥ y
or
y ≤ 5

Hey! So, you know she bought two clipboards. You're going to want to add 2.23 and 2.23 together, which is 4.46. Sheila only bought one notebook, so you simply add 4.46 and 0.58 together, which is 5.05. But, wait! She paid with a 10 dollar bill. Now, we have to take 5.05 out of 10.00, which is 4.95. Now, our answer is going to be $4.95 in change. I hope I helped! :)
