In this video I explain how to graph the derivative, f'(x), of a function if you're only given its graph. I break down the process into a simple step by step...
You are given the graph of `f'(x)`, and your task is to reconstruct the graph of `f(x)`. Once you can do this well, you are ready for the first derivative test. Explore. The graph of `f'(x)` is shown in red. Drag the blue points up and down so that together they follow the shape of the graph of `f(x)`. As a help, the three large green points ...
Graph f(x) Given f'(x) Added Sep 29, 2016 by rwlmath in Mathematics Enter in coefficients for x cubed, x squared, x and a constant for a derivative, and the original function will be graphed in the condition where the y-intercept is zero.
But! you can sketch the graph of f(x) using the information you have. You know that at x = 1, 6, 8 the graph of f(x) has a horizontal tangent line. So, all up and down the vertical lines x =1, x = 6, x = 8, draw short horizontal line segments--these are the tangent lines. You know that at x= 5, the graph of f(x) has a tangent line with slope 3.
Remember: f ()x determines whether a function is increasing or decreasing, so always use the sign of f ()x when determining and justifying whether a function f ()x is increasing or decreasing. Situation Explanation f ()x is increasing on the interval (, )ab f ()x is increasing on the interval (, )abbecause fx () 0 f ()x is decreasing on the ...
Working Rule to Find Value of a Function From Its Graph. Find the value of a function f(x) when x = a. Step 1 : Draw a vertical line through the value 'a' on x-axis. Step 2 : Mark the point of intersection of the line x = a and graph of f(x). Step 3 : Draw an horizontal line from the point of intersection to y-axis. Step 4 :
How to determine the value of a function \(f(x)\) using a graph. Go to the point on the \(x\) axis corresponding to the input for the function. Move up or down until you hit the graph. The \(y\) value at that point on the graph is the value for \(f(x)\). How to use the vertical line test to determine if a graph represents a function
Plot the Ordered Pairs: On the graph paper, mark each ordered pair as a point. The x-coordinate represents the input, and the y-coordinate the output value.. Draw the Curve or Line: Connect the points smoothly.If it is a straight line, ensure you’ve plotted at least two points, one being the y-intercept ( (0, b) ) where the graph crosses the y-axis, and calculate the slope as the rise over ...

Graphing the Second Derivative Given the Graph of the Original Function. You are shown the graph of \(y = f(x)\). Use your mouse from the very far left to the far right in the xy-plane, not too fast, to sketch the graph of \(y = f''(x)\). Behind your sketch, the correct graph of the second derivative function will be sketched. New Function Try ...
Linear: f(x) = mx + b; Quadratic: f(x) = ax² + bx + c; ... Customize your graph window using the X Min, X Max, Y Min, and Y Max fields. Choose grid size and resolution for better control over detail and speed. Use the checkboxes to show or hide elements like axes and labels.

Recall that relation is the name given to a collection of ordered pairs. In Figure \(\PageIndex{2}\)(b) we’ve plotted each of the ordered pairs in the relation R. This is called the graph of the relation R. ... However, what is important is the fact that we’ve captured the “important features” of the graph of \(f(x)=56-x-x^{2}\). Note ...
Graph the linear function f given by f (x) = 2 x + 4 Solution to Example 1. You need only two points to graph a linear function. These points may be chosen as the x and y intercepts of the graph for example. Determine the x intercept, set f(x) = 0 and solve for x. 2 x + 4 = 0
