Exercise 4 Page 299

Let's consider an exponential equation where the left-hand side is an exponential function and the right-hand side is a linear function. We can solve an equation like this by graphing. To do this, we should graph both functions together. At the intersection points, both functions have the same $y\text{-value},$ and thus, the corresponding $x\text{-value}$ satisfies the equation. Therefore, the $x\text{-coordinates}$ of the intersection points are the solutions to the equation.
