How to write the answer to an absolute value equation

At point B, the slope is negative. Fundamental Rules of Derivatives Now the company would like a precise measurement of the the instantaneous rate of change, or the slope of the line tangent to the point 2, 5. Plug the x value of the point into the first derivative. Practice finding the first derivative of the polynomial expressions below. The steps for finding a function's first derivative are explained and illustrated in the following animation. This maximum point occurs at the point at which the derivative is zero. This means that in order to produce 1 million more bolts, the company will have to produce 4 million fewer nuts. The company wants to know more about the production tradeoffs, or average rate of change, between the number of nuts and bolts that can be produced at a rate of 5 million nuts, which corresponds to 2 million bolts produced. The sign of the slope indicates to managers the nature of the change in the dependent variable for a given change in the independent variable. When the first derivative is positive, the individual output continues to increase as people are added to the team. Writing an Equation with a Known Solution If you have values for x and y for the above example, you can determine which of the two possible relationships between x and y is true, and this tells you whether the expression in the absolute value brackets is positive or negative.

This is the solution for equation 2. Because a secant line is straight, its slope can be determined using the rise-over-run formula, which is discussed in the Linear Functions portion of the Algebra section of this course. High bandwith First Derivatives The slope of a secant line only estimates rate of change.

For help finding derivatives of other types of functions, consult a calculator or a business math text. The secant line that passes through the function at these two points is shown below. This sensitivity is expressed in the value of the slope and is sometimes called the "rate of change" because it measures the rate of change in y as a result of a change in x.

Look at the following example of a function and its first and second derivative. Fundamental Rules of Derivatives Now the company would like a precise measurement of the the instantaneous rate of change, or the slope of the line tangent to the point 2, 5. Slope tells you the sensitivity of the y variable to changes in the x variable. This demonstrates how the average rate of change can closely approximate the instantaneous rate of change when the points chosen are very close together. Second Derivatives The second derivative can be written as f " x , which can be expressed verbally as "f double prime of x. Plug in known values to determine which solution is correct, then rewrite the equation without absolute value brackets. As the absolute value of the slope increases, so does the sensitivity of y to changes in x.

Updated April 25, By Chris Deziel You can denote absolute value by a pair of vertical lines bracketing the number in question. In this function, f x is the number in millions of nuts produced and x is the number in millions of bolts produced. At point B, the slope is negative.
