Answer:
A. (f+g)(x) means add the two functions, f and g
since f is 2x-2 and g is 6x, you'll just add them together
(f+g)(x)=2x-2+6x = 8x+2
B. (f-g)(x) means subtract the two functions, f and g
since f is 2x-2 and g is 6x, you'll just subtract
(f-g)(x)=2x-2-6x = -4x+2
C. (g-f)(x) I think you're getting the hang of it!
=6x-(2x-2) just be sure to put the second function in parentheses because you're subtracting the whole thing
=6x-2x+2 = 4x+2
D. (g+f)(x) try this on your own and check here
6x+(2x-2) = 6x+2x-2 = 8x-2
Step-by-step explanation:
to add or subtract functions, don't let the function notation throw you off. Pretend each one is just a number and you just add or subtract the whole thing. You got it! Next they will give you something like find (f+g)(5). All that means is add the two functions like in part a, and then in the final answer, plug in 5 instead of x. For example (f+g)(5) = 8x+2 = 8(5) +2 = 42

What are the statements? Cannot answer without them.
The statements that agree with the graph of the equation are as follows:
<span>4.the function is decreasing over the interval (−4, ∞).
</span><span>1.the domain is {x|x ≤ –2}.
I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.

Answer:
24-x=y (number of points scored in the first half)
if x equals 20, then we can rewrite the equation to
24-20=y
4=y
Well if he gets one of hes green balls out 12 times the next time he has a chance of 18%
