Solving it with separation of variables results in the general. Sal is given a table of values of an exponential function and he analyzes it in order to find the common ratio and the initial value.Watch the next lesson: h. Then write a function that results from the given transformation. Assuming a quantity grows proportionally to its size results in the general equation dy/dxky. \( \bigstar \) For the following exercises, start with the graph of \(f(x)=4^x\).

Exponential functions can grow or decay very quickly.

As \(x\rightarrow \infty, f(x)\rightarrow 2\) As \(x\rightarrow -\infty, f(x)\rightarrow \infty\) Reflect over y-axis, y's get stretched by a factor of 3, up 2.į: Construct an Equation Given a Description An exponential function represents the relationship between an input and output, where we use repeated multiplication on an initial value to get the output for any given input. And what I want to do is figure out what is m of six going to be. As \(x\rightarrow \infty, f(x)\rightarrow -\infty\) As \(x\rightarrow -\infty, f(x)\rightarrow -1\) Reflect over x-axis, y's stretched by a factor of 5, down 1ĩ7. Voiceover So we have the graph of an exponential function here, and the function is m of x. What will Krysti’s balance be after twenty years if interest is compounded semi-annually? If one thousand dollars is invested in an online savings account, earning 8% per year, compounded continuously, how much will be in the account after ten years?
