Theorem 6.2.2. If X is any random variable and c is any constant, then V(cX) = c2V(X) and V(X + c) = V(X) . Proof. We turn now to some general properties of the variance. Recall that if X and Y are any two random variables, E(X + Y) = E(X) + E(Y). This is not always true for the case of the variance.

The function, "f" is defined by the following rule. f(x)=x5 Complete
Integration by parts is a method to find integrals of products: ∫ u ( x) v ′ ( x) d x = u ( x) v ( x) − ∫ u ′ ( x) v ( x) d x. or more compactly: ∫ u d v = u v − ∫ v d u. We can use this method, which can be considered as the "reverse product rule ," by considering one of the two factors as the derivative of another function.

How do you graph f(x) = x^24x + 5? Socratic
A function, by definition, can only have one output value for any input value. So this is one of the few times your Dad may be incorrect. A circle can be defined by an equation, but the equation is not a function. But a circle can be graphed by two functions on the same graph. y=√ (r²-x²) and y=-√ (r²-x²)
Answered The graph below is the function f(x) 5… bartleby
The Derivative tells us the slope of a function at any point. There are rules we can follow to find many derivatives. For example: The slope of a constant value (like 3) is always 0 The slope of a line like 2x is 2, or 3x is 3 etc and so on. Here are useful rules to help you work out the derivatives of many functions (with examples below ).

Using implicit differentiation Using chain rule Quotient Rule Formula Proof Using Derivative and Limit Properties To prove quotient rule formula using the definition of derivative or limits, let the function f (x) = u (x)/v (x). ⇒ f' (x) = lim h → 0 [f (x + h) - f (x)]/h = lim h → 0 u ( x + h) v ( x + h) − u ( x) v ( x) h

Jan 21, 2014 at 15:57 Add a comment 2 Answers Sorted by: 14 The graph of $f (-x)$ is the mirror image of the graph of $f (x)$ with respect to the vertical axis. The graph of $-f (x)$ is the mirror image of the graph of $f (x)$ with respect to the horizontal axis. A function is called even if $f (x)=f (-x)$ for all $x$ (For example, $\cos (x)$).
SOLUTION what is a domain of f(x)=52x
We say "f of x equals x squared" what goes into the function is put inside parentheses () after the name of the function: So f (x) shows us the function is called " f ", and " x " goes in And we usually see what a function does with the input: f (x) = x2 shows us that function " f " takes " x " and squares it. Example: with f (x) = x2:

lf c is any real number and if f(x) = c for all x, then f ' (x) = 0 for all x . That is, the derivative of a constant function is the zero function. It is easy to see this geometrically. Referring to Figure 1, we see that the graph of the constant function f(x) = c is a horizontal line. Since a horizontal line has slope 0, and the line is its.

Answered Differentiate f (x) = V x+ V 3D bartleby
Using the formulas from above, we can start with x=4: f (4) = 2×4+3 = 11 We can then use the inverse on the 11: f-1(11) = (11-3)/2 = 4 And we magically get 4 back again! We can write that in one line: f-1( f (4) ) = 4 "f inverse of f of 4 equals 4" So applying a function f and then its inverse f-1 gives us the original value back again:
