2 Given \(y = \mathrm { e } ^ { k x }\), where \(k\) is a constant, find \(\frac { \mathrm { d } y } { \mathrm {~d} x }\)
Circle your answer. $$\frac { \mathrm { d } y } { \mathrm {~d} x } = \mathrm { e } ^ { k x } \quad \frac { \mathrm {~d} y } { \mathrm {~d} x } = k \mathrm { e } ^ { k x } \quad \frac { \mathrm {~d} y } { \mathrm {~d} x } = k x \mathrm { e } ^ { k x - 1 } \quad \frac { \mathrm {~d} y } { \mathrm {~d} x } = \frac { \mathrm { e } ^ { k x } } { k }$$
