Question 863160
If you want to graph this, then using a graphing calculator gives you


{{{ drawing(500, 500, -10, 10, -10, 10,
grid(1),
 graph( 500, 500, -10, 10, -10, 10,0,5^x)

)}}}


Note: this graph goes through the points (0,1), (1,5), (2,25)


Another note: this graph NEVER crosses the x axis (even though it looks like it does). It just gets closer and closer to it. The horizontal asymptote is {{{y = 0}}}
