Exponential and Logarithmic Functions

Graphing an exponential function and its asymptote: $f(x)=b^x$ or $f(x)=-b^x$dots

Graph the exponential function.

$f(x)=-(\frac{1}{2}{)}^x$

Plot five points on the graph of the function, and also draw the asymptote. Then click on the graph$-$a$-$function button.
