Problem

Describe how to transform the graph of $f$ into the graph of g. Sketch the graphs by hand and support your answer with a grapher. \[ \begin{array}{l} f(x)=e^{x} \\ g(x)=e^{-10 x} \end{array} \] To transform the graph of $\mathrm{f}$ into the graph of $\mathrm{g}$,

Solution

Step 1 :The transformation from the graph of \(f(x) = e^x\) to \(g(x) = e^{-10x}\) involves two steps.

Step 2 :The first step is a reflection. The negative sign in the exponent of \(g(x) = e^{-10x}\) indicates a reflection of the graph of \(f(x) = e^x\) in the y-axis. This means that the graph of \(g(x)\) will be a mirror image of the graph of \(f(x)\) with respect to the y-axis.

Step 3 :The second step is a horizontal compression. The factor of 10 in the exponent of \(g(x) = e^{-10x}\) indicates a horizontal compression of the graph of \(f(x) = e^x\) by a factor of 10. This means that the graph of \(g(x)\) will be 'squeezed' horizontally towards the y-axis by a factor of 10 compared to the graph of \(f(x)\).

Step 4 :So, to transform the graph of \(f(x) = e^x\) into the graph of \(g(x) = e^{-10x}\), you would first reflect the graph of \(f(x)\) in the y-axis, and then compress it horizontally by a factor of 10.
