Learn to construct linear and exponential functions from data with Khan Academy's detailed lessons and examples.

Write exponential functions of the basic form f(x)=a⋅rˣ, either when given a table with two input-output pairs, or when given the graph of the function.

We can graph an exponential function, like y=5ˣ, by picking a few inputs (x-values) and finding their corresponding outputs (y-values). We'll see that an exponential function has a horizontal …

Here is how we can write an equation for an exponential function from a table of values: 1. Determine the common ratio. For example, if we see that every time x increases by 1, y is …

The best way to graph exponential functions is to find a few points on the graph and to sketch the graph based on these points. To find a point on the graph, select an input value and calculate …

Learn algebra through engaging lessons on exponential and logarithmic functions at Khan Academy.

What does it mean for something to change exponentially? Let's learn about a new family of functions, and use these exponential functions to analyze real-world scenarios.

Learn the difference between exponential and linear growth with Khan Academy's engaging video lessons on mathematical models and real-world applications.

Given a graph of a line, we can write a linear function in the form y=mx+b by identifying the slope (m) and y-intercept (b) in the graph. GIven a graph of an exponential curve, we can write an …
