Answer:
F(x)=
+7cosh(x)+C
Step-by-step explanation:
The function is f(x)=3ˣ+7sinh(x), so we can define it as f(x)=g(x)+h(x) where g(x)=3ˣ and h(x)=7sinh(x).
Now we have to find the most general antiderivative of the function this means that we have to calculate
wich is the same as
The sum rule in integration states that the integral of a sum of two functions is equal to the sum of their integrals. Then,
=
1- 
this is because of the rule for integration of exponencial functions, this rule is:
, in this case a=3
2-
, number seven is a constant (it doesn´t depend of "x") so it "gets out" of the integral.
The result then is:
F(x)=

The letter C is added because the integrations is undefined.
Answer:
C. -3
Step-by-step explanation:
Start from (-1,4) drop down -6 spots then move over 2 spot to end up at (1,2). This is the same as writing -6/2 which equals -3.
If you start from other point (1,2) you'll have to move up 6 then back -2 to get to (-1,4) which is also -6/2 like above and slope is still -3.
Remember y = mx + b
m is the slope and with above example -6/2 top number is rise which move up/down and bottom number is run which move left/right.
Another way of solving it is:
(y2 - y1) / (x2 - x1)
4 - (-2) / -1 - 1
6 / -2
-3
Answer:
No she is not correct because they ARE correct
Step-by-step explanation:
to figure out if it's proportional you do y over x and simplify...
they would all equal 5
