Write down the exponential equation, y = x^2, as your exponential equation. Enter this equation into the first equation text box of your calculator.
Write down the equation, y = 0.5*x^2, as your exponential equation. Enter this equation into the second equation text box of your calculator.
Write down the equation, y = 2^x, as your exponential equation. Enter this equation into the third equation text box of your calculator.
Press the "graph," "calculate" or "plot" button on the calculator to graph the three equations on your calculator's screen.
Use the zoom, pan and intersection point controls if your calculator has them to locate the point(s) where each of the equation graphs intersect each other. Otherwise, visually inspect the intersection of the graphed exponential equations to find the point (x,y coordinates) where the exponential functions intersect.
Print or save the graph with the "Print" and "Save" buttons if the calculator offers them.
Reset the minimum and maximum vales for the dimensions of the graph and the spacing between divisions, if the calculator offers that feature. Enter in the previous exponential equations you used and graph them again to look at the graphs of the exponential functions over the range of values you specified.
