Final answer:
To solve the equation by graphing, we can plot the graph of y = -2x - 3 - (3^x + 2) and find the x-axis intercepts.
Step-by-step explanation:
To solve the equation -2x-3=3^x+2 by graphing, we need to transfer the equation into the form y = 0. We rearrange the equation to get -2x - 3 - (3^x + 2) = 0.
Next, we can plot the graph of y = -2x - 3 - (3^x + 2) and the x-axis intercepts will give us the solutions to the equation. Using a graphing calculator or software, we can find that x = 0.027 atm is the solution.
