The cylinder is a clue to use cylindrical coordinates. Taking
and
, we then are forced to use
. So the parameterization of the intersection of the plane and cylinder is
To get the surface, we can introduce a second parameter
that "contracts" the elliptical intersection to a point. The simplest way to do this is to use
with
and
.
Answer:
C. -∞ < x < ∞
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values can be any number. Therefore, we have all real numbers as our domain:
(-∞, ∞) or -∞ < x < ∞
Answer:
-21.1 and 24.1
Step-by-step explanation:
-8.2*4 + 3.9*3=-21.1
5.1*3 - (-2.2*4)=24.1
Well 21 times 2 is 42 and 1/3 of 21 is 7 so 42+7 is 49. hope this is right
The statement that describes better about function is "Both functions are increasing, but function g increases at a faster average rate." since option (c) is correct.
Given the table
x f(x)
-2 -46
-1 -22
0 -10
1 -4
2 -1
We have to choose which statement describes better about function
Let us assume 
at x=0, f(0)=-10
So, -10 =a+c
Similarly, by satisfying the above table in the f(x)
So we can say that f(x) is an increasing function.
ln(1/3) < 0
So, g^ \prime (x) > 0
So, g(x) is an increasing function.
For any x∈f(x) and x∈g(x) 
So, g increases at a faster average rate
Thus, Both functions are increasing, but function g increases at a faster average rate.
