4. Solving Exponential Equations

Continue to next subchapter

Exercise 36 Page 303

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 a function. 5^(-2x+3)=-6^(x+5) ⇒ ly=5^(-2x+3) y=-6^(x+5)

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.

Unfortunately, there are no points of intersection for these graphs. Therefore, there are no solutions to the equation.
