(a) complete the table to find an interval containing the solution of the equation, (b) use a graphing utility to graph both sides of the equation to estimate the solution, and (c) solve the equation algebraically. Round your results to three decimal places. $$e^{3 x}=12$$ $$\begin{array}{|l|l|l|l|l|l|}\hline x & 0.6 & 0.7 & 0.8 & 0.9 & 1.0 \\\hline e^{3 x} & & & & & \\\hline\end{array}$$

Key Concepts

Exponential Functions

Exponential functions are mathematical expressions where the variable appears as an exponent, typically formulated as f(x) = e^(ax) with a constant multiplier. They are critical in understanding growth and decay processes in various fields such as finance, biology, and physics, and form the basis for many natural phenomena that exhibit rapid changes.

Logarithms

Logarithms serve as the inverse operations of exponentiation, allowing one to solve equations where the variable is located in the exponent. By applying logarithms to both sides of an equation like e^(3x) = 12, one can use the property ln(e^(3x)) = 3x to isolate and solve for x, making logarithms an essential tool in algebra and calculus.

Graphical Methods for Solving Equations

Graphical methods involve plotting the functions represented on both sides of an equation to visually identify the points at which they intersect, representing approximate solutions. This technique not only provides an intuitive understanding of the behavior of functions but also serves as a useful check for algebraic solutions.

Numerical Approximation Techniques

Numerical approximation techniques, such as constructing a table of values or performing interval bisection, are used to estimate the solution of equations when an exact solution is not readily available. By evaluating the function at discrete points and identifying intervals where the sign of the function changes, one can narrow down and approximate the root with a desired level of accuracy.
