If you know two points that fall on a particular exponential curve, you can define the curve by solving the general exponential function using those points. In practice, this means substituting the points for y and x in the equation y = abx. The procedure is easier if the x-value for on...
Find a formula in the form f(x)=a(b)^{x} , for the exponential function that passes through the two points given (0,4) and (0,256). Find the equation for the exponential function f(x)=b a^x that passes through the two points 1) (0,2) and (1,5) 2) (-2.32) and (2, ...

If neither of the data points have the form(0,a)(0,a), substitute both points into two equations with the formf(x)=abxf(x)=abx. Solve the resulting system of two equations to findaandb. Write the exponential function,f(x)=abxf(x)=abx. ...
To write the equation of an exponential function graph, pick two coordinate points on the curve then plug each coordinate in for x and y in the equation y = ab^x to get two equations. Divide the equation with the larger exponent by the equation with the smaller exponent. The a terms wi...
We can understand the process ofgraphingexponential function by taking some examples. Let us graph two functions f(x) = 2xand g(x) = (1/2)x. To graph each of these functions, we will construct a table of values with some random values of x, plot the points on the graph, connect ...
