Exercise 36 Page 303

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. \begin{gathered} 5^{\text{-}2x+3}=\text{-}6^{x+5} \quad\Rightarrow\quad ly=5^(-2x+3) y=-6^(x+5) \end{gathered} Now, to graph the functions, we press the Y= button and type the equations in the two first rows. Having written the functions, we push GRAPH.
