Difference Quotient: Formula, Calculator, Examples. Difference Quotient is used to calculate the slope of the secant line between two points on the graph of a function, f. Just to review, a function is a line or curve that has only one y value for every x value. Currency Converter Full currency converter. Has a database of historical values, and also allows bank commissions in the calculation. Let f(x) = x^2 / (x^2 + 1). Calculate ( f(2+h) - f(2-h ... Aug 15, 2010 · I only know how to do this derivative thing when we have to find ( f(x+h) - f(x-h) ) / h so how or what do I do for this question? If I use the normal formula I get (x-h)^2 - (x+h)^2 is this correct? And where do I go from there? If I substitute 2 into f(x) so f(2) I get (4/5 +h) - (4/5 - h) / 2h am I on the correct track AND how do I solve this question?
The given function is the product of two other function and we need to find out the derivative at the given point. To solve this problem, we'll take the derivative and use the product rule. It is

Given f(x) = 2x - 3, find f(x+h)? | Yahoo Answers Oct 02, 2011 · Given f(x) = 2x - 3, find f(x+h)? Answer Save. 2 Answers. Relevance. Josh B. Lv 4. 8 years ago. Favorite Answer. If you want to learn, I will teach you. Basically, you plug in the expression (x+h) for x in the equation 2x - 3. This will make the equation look like this: 2(x+h) - 3. Simplify by foiling. Multiply 2 … The difference quotient (f(x+h)-f(x))/h - Math Central Find the difference quotient of f, f(x+h)-f(x)/h, h does not equal 0, Helen, You will find that what you have after the last step will divide by h since f is a polynomial. When you get to calculus (which is what this is in preparation for!) you will learn how to use limits to deal with other functions. Good Hunting! Difference Quotient - analyzemath.com Definition of Difference Quotient Let f be a function whose graph is shown below. A and B are points on the graph of f. A line passing trough the two points A ( x , f(x)) and B(x+h , f(x+h)) is called a secant line. The slope m of the secant line may be calculated as follows: Checking Answers Using Algebra Calculator - MathPapa
Find the difference quotient f(x + h) - f(x)/h f(x) = x^2 - x f(x) = x^2 + 2x f(x) = x^2 - 3x + 2 f(x) = x^2 - 2x + 5 in Exercises 45-52, find the average rate of change of the function f(x) = x^3 f(x) = 1/x f(x) = 1 - 2x f(x) = 9 - x^2 in Exercises 53-78, graph the piecewise-defined functions.
