Question

Use the crossing-graphs method to solve the given equation. (Round youranswers to two decimal places.) 3^x– 10 = 0x=_______

Answer 1

you have to rearrange the equation to:

$3^x=10$

Left side and right side equations become:

$\begin{gathered} y=3^x \\ \text{and} \\ y=10 \end{gathered}$

The first equation is a exponential and second one is a horizontal line. Below I show the two individual graphs:

First

Second

Now, you put the 2 graphs in a single coordinate system and see the intersection point. Shown below:
