What is the domain of ln x2 plus 2x minus 8?

The ln(y) is only defined for positive values of y. So, ln(x2 + 2x - 8) is defined only for x2 + 2x - 8 > 0 ie for x< -4 or x > 2 So the domain is x< -4 or [union] x > 2


What is the dervative of x pwr x pwr x?

For the function: y = x^x^x (the superscript notation on this text editor does not work with double superscripts) To solve for the derivative y', implicit differentiation is needed. First, the equation must be manipulated so there are no x's raised to x's on the right side of the equation. So, both sides of the equation must be input into a natural logarithm, wherein we can use the properties of logarithms to remove the superscripted powers of the right side: ln(y) = ln(x^x^x) ln(y) = xxln(x) ln(y)/ln(x) = xx ln(ln(y)/ln(x)) = xln(x) eln(ln(y)/ln(x)) = exln(x) ln(y)/ln(x) = exln(x) ln(y) = ln(x)exln(x) Now there are no functions raised to functions (x's raised to x's). Deriving this equation yields: (1/y)(y') = ln(x)exln(x)(x(1/x) + ln(x)) + exln(x)(1/x) = ln(x)exln(x)(1 + ln(x)) + exln(x)(1/x) = exln(x)(ln(x)(1+ln(x)) + (1/x)) Solving for y' yields: y' = y[exln(x)(ln2(x) + ln(x) + (1/x))] or y = xx^x ln(y) = ln(x)x^x ln(y) = xxln(x) ln(y) = exlnxln(x) y'/y = exlnx[ln(x) + 1)ln(x) + exlnx(1/x) y' = y[exlnx(ln2(x) + ln(x) + 1/x)] y' = xx^x[exlnx(ln2(x) + ln(x) + 1/x)]

What is the domain of the graph of y equals 2 to the power of x?

The domain of y = 2x is [0, +infinity].


What is the domain and range for y equals 0 to 25 and x equals 0 to 10?

The domain is the x values, so x = 0 to 10. The range is the y values, so y = 0 to 25.


What is the range of y equals -sin x?

The range of -sin x depends on the domain of x. If the domain of x is unrestricted then the range of y is [-1, 1].


How do you Differentiate and Integrate y equals 3 to the power of x?

dy/dx = 3^x * ln(3)integral = (3^x) / ln(3)To obtain the above integral...Let y = 3^xln y = x ln 3y = e^(x ln 3)(i.e. 3^x is the same as e^(x ln 3) ).The integral will then be 3^x / ln 3 (from linear composite rule and substitution after integration).


How do you use logarithmic differentiation for yxex?

I take this to be y = xex.Proceeding formally (ie, without regard to restrictions on the domain of ln x):Take natural logarithms of 'both sides' of above equation: ln y = ln x + xImplicit differentiation: y'/y = 1/x + 1Multiply both sides by y: y' = y ( 1/x + 1 )Replace y by its definition as a function: y' = xex ( 1/x + 1 ).


What is the range of y equals tan2x?

It depends on the domain of x.


What is the derivative of x to the power of ln x?

I don't believe that the answer is ln(x)x^(ln(x)-2), since the power rule doesn't apply when you have the variable in the exponent. Do the following instead:y x^ln(x)Taking the natural log of both sides:ln(y)ln(x) * ln(x)ln(y) ln(x)^2Take the derivative of both sides, using the chain rule:1/y * y' 2 ln(x) / xy' 2 ln(x)/ x * yFinally, substitute in the first equation, y x^ln(x):y' 2 ln(x) / x * x^ln(x)y'2 ln(x) * x ^ (ln(x) - 1)Sorry if everything is formatted really badly, this is my first post on answers.com.
