Activity 3.3.3.
By graphing \(f(t) = e^t\) and appropriate horizontal lines, estimate the solution to each of the following equations. Note that in some parts, you may need to do some algebraic work in addition to using the graph.
(a)
\(e^t = 2\)
(b)
\(e^{3t} = 5\)
(c)
\(2e^t - 4 = 7\)
(d)
\(3e^{0.25t} + 2 = 6\)
(e)
\(4 - 2e^{-0.7t} = 3\)
(f)
\(2e^{1.2t} = 1.5e^{1.6t}\)
