 * Addition of Ordinates **

The addition of ordinates process can be used to add graphs including exponential graphs and log graphs.

Recall that f(x) + g(x) is only defined where __both__ f(x) __and__ g(x) are defined.

Hence domain(f + g) = domain(f) ∩ domain(g)


 * Example 1 **

Use addition of ordinates to sketch the graph of y = e x + e –x. media type="custom" key="8056348" media type="custom" key="8056364" ... media type="custom" key="8056366" ... media type="custom" key="8056412"
