Use the calculator to graph two different functions, one for each side of the equation.
No solutions
Practice makes perfect
To solve the equation by graphing, we first have to create two functions. Each side of the given equation will become a function.
(1/2)^(7x+1)=-9 ⇒ ly=(1/2)^(7x+1) y=-9
Now we want to draw the graphs of these two functions using a calculator. We can do this by pressing the Y= button and typing the equations in the two first rows.
The graph we have is not clear. Let's have a closer view by changing the viewing window. We do this by pushing WINDOW.
Unfortunately, there are no points of intersection for these graphs. Therefore, there are no solutions to the equation.
