how to determine f x from a graph

how to determine f x from a graph F x m x b Here m is the slope of the line and b is the y intercept By finding these two parameters from my table I can predict output values for new input values Extrapolation is most reliable when the new inputs aren t too far from the data I originally used to construct the function Deriving the Function Equation from a Graph

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 This video explains how to determine a function value given the graph of a function but not the function rule Complete Library mathispower4u co

Assuming that f is a polynomial can I just pick the graphs of of f f and f visually by recalling that a derivative of a polynomial will produce an polynomial equation of a 1 lesser degree That means the roots of f will have the greatest We typically construct graphs with the input values along the horizontal axis and the output values along the vertical axis The most common graphs name the input value x x and the output value y y and we say y y is a function of x x or y f

F x sqrt x is a function If you input 9 you will get only 3 Remember sqrt x tells you to use the principal root which is the positive root If the problem wanted you to use the negative root it would say sqrt x Explore math with our beautiful free online graphing calculator Graph functions plot points visualize algebraic equations add sliders animate graphs and more
