Writing Equations Of Exponential Functions From Tables Youtube Join me as i show you how to write equations of exponential functions from graphs, tables and word problems.my name is lauren casias. i am an 8th grade math. Before graphing, identify the behavior and create a table of points for the graph. since b = 0.25 b = 0.25 is between zero and one, we know the function is decreasing. the left tail of the graph will increase without bound, and the right tail will approach the asymptote y = 0. y = 0. 6.1 exponential functions college algebra 2e. Find an exponential function that passes through the points (− 2, 6) and (2, 1). solution. because we don’t have the initial value, we substitute both points into an equation of the form f(x) = abx, and then solve the system for a and b. substituting (− 2, 6) gives 6 = ab − 2. substituting (2, 1) gives 1 = ab2.

Finding Exponential Function Equations From A Table And Graph Youtube 6.1 exponential functions college algebra 2e.

Example: writing an exponential function given its graph find an equation for the exponential function graphed below. answer: we can choose the y intercept of the graph, [latex]\left(0,3\right)[ latex], as our first point. this gives us the initial value [latex]a=3[ latex]. Enter the given exponential equation in the line headed “y 1 =”. enter the given value forf(x) f(x) in the line headed “y 2 =”. press [window]. adjust the y axis so that it includes the value entered for “y 2 =”. press [graph] to observe the graph of the exponential function along with the line for the specified value off(x). f(x).
