Use the calculator to graph two different functions, one for each side of the equation.
No solution
Practice makes perfect
To solve the equation by graphing, we first have to create two functions. Each side of the given equation will become its own equation.
- 4=6^(4x-3) ⇒ ly=- 4 y=6^(4x-3)
Now we want to draw these graphs using a calculator. We can do this by pressing the Y= button and typing the equations in the two first rows.
Before we graph these functions, notice that the exponent of 6 is 4x-3, so the function will grow very quickly. In order to accommodate this issue, we should change the viewing window. Let's restrict the x-axis.
-2 < x < 2
We can do this by pushing WINDOW. Let's now draw the graphs.
There is no point of intersection of these lines and therefore there are no solutions.
