Answer:
(f + g)(4) = 9
Step-by-step explanation:
We have that:
f = {(-1,-3), (1,1),(2,3),(4,6)}
this means that:
f(-1) = -3
f(1) = 1
f(2) = 3
f(4) = 6
and we also know that:
g = {(-1,-1),(1,7),(4,3)}
hich means that:
g(-1) = -1
g(1) = 7
g(4) = 3
Now we want to find:
(f + g)(4)
For the general case of two functions f(x) and g(x)
(f + g)(x) = f(x) + g(x)
Then:
(f + g)(4) = f(4) + g(4)
and we know both of these values, so we can just replace them:
(f + g)(4) = f(4) + g(4) = 6 + 3 = 9
Then we get:
(f + g)(4) = 9
Answer:
x = -6
Step-by-step explanation:
-1.5x = 9 Divide the -1.5 on both sides
x = -6
Plug in the answer to make sure it works.
-1.5(6) = 9
9 = 9

Step-by-step explanation:
We have been given two functions 
and 
.
Now questions is asking about what do the graphs of the two even degree functions and have in common.
By property of even edgree polynomial we know that if it starts from top then it will also end at the top.
If it starts from bottom then it will also end in bottom.
In simple words, we can says that even degree polynomial starts and ends in same direction.
Given functions and are also even degree polynomial so common thing about them is that they will start and end in the same direction. (Upward). You can also check the attached graph of both for better guidance.
Use the same to solve the rest of the problems. Hope this helps:)
