Graphing an exponential function can be tricky. We are familiar with the graph of $$e^x$$. But what if a bunch of such exponential expressions is clubbed together? I.S.I.’s Test of Mathematics has a problem related to this.

The adjoining figure is the graph of

(A) $$y = 2 e^x$$

(B) $$y = 2^{-x}$$

(C) $$y = e^x + e^{-x}$$

(D) $$y = e^x – e^{-x} + 2$$
