Graphing the exponential (TOMATO Objective 699)

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) \( y = e^x – e^{-x} + 2 \)
