Evaluate the function at the given value of the independent variable?

Show me how u got it. Evaluate the function at the given value of the independent variable. Simplify the results.



f(x) = 1/sqrt(x-1)



Find:



[f(x) - f(2)] / (x-2)Evaluate the function at the given value of the independent variable?
[f(x) - f(2)]/(x-2)=[1-(sqrt(x-1)] / [sqrt(x-1) (x-2)]Evaluate the function at the given value of the independent variable?
f(2) = 1/sqrt(2-1) = 1/sqrt(1) = 1



f(x) - f(2) = [1/sqrt(x-1)] -1 =[1-sqrt(x-1)]/sqrt(x-1)



so the answer is [1-sqrt(x-1)] / [(x-2)sqrt(x-1)]

Given the volume and mass, what is the independent variable and which is the dependent variable?

which is the dependent variable and which is the independent variable. and why? thanksGiven the volume and mass, what is the independent variable and which is the dependent variable?
volume depends on the temperature and pressure, it is a dependent variable .



Mass does not change, it is an independent variable .

What is the dependent variable and the independent variable of, lead paint is really harmful?

what is a example of dependent variable and independent variable of lead paint really harmful?What is the dependent variable and the independent variable of, lead paint is really harmful?
The independent variable is the one the researcher (you) changes, so it would be the amount of lead.



The dependent variable is the one which "depends" on the independent variable, in that the dependent variable responds to the changes if there is a true "cause-and-effect". In this case, the type or degree of "harm" to a patient. You'd expect that with higher levels of lead, the effects would be more severe.



Hope this isn't an experiment you were planning to carry out yourself.

What are some independent variables to determine gas prices (dependent variable) in the U.S ?

I came up with an independent variable on prices of substitutes such as the price of diesel fuel and substitutes of alternatives such as fuel cells in production. I also have 3 dummy variables which are unusual weather, 2 seasons (winter, summer probably), and middle east issue such as if there is a war during that time. I would like some help to see what more independent variables i can work with and can easily obtain the data. Oh yeah and this would probably be on a national bases. Thanks peopleWhat are some independent variables to determine gas prices (dependent variable) in the U.S ?

Levels of the independent variable(s): no idea from info given

Dependent variable(s) endurance performance

Measurement scale of the dependent variable(s) no idea from info given

The control would be the placeboWhich is the independent variable and which is the dependent variable?
Independent is the green tea extract



Dependent is the caffeine and placebo

What is the independent variable of this function?

A rental agency charges $23.00 per day and $0.10 per mile for a rental car. The independent variable in this function is....What is the independent variable of this function?
$.10 per mile is the indep variable because it will vary with each user. The $23 per day is same for all users.

What is my independent variable & my dependent variable?

I am doing a science fair project my questions is "which beach works best" I bought 2 bleaches a dollar store brand one %26amp; Clorox. I bought 2 shirts %26amp; have equally gotten them dirty by placing stains of the same substance on both in the same area. Now I just need to figure our what it my independent variable, dependent variable and my controlled variables. HELP PLEASE!What is my independent variable %26amp; my dependent variable?
The independent variable, or IV is your two bleach brands,

The store brand one and Clorox, since YOU are the one changing it.

The dependent variable is how well they work,

In this case, how well the bleach works on the shirt.
