whehn x = 0, h(x) and k(x) both equal 1.
in the graph, h(x) is equal to y and k(x) is equal to y.
this is done for graphing purposes.
the coordinates are in (x,y) format.
x is the value of the coordinate point along the x-axis.
y is the value of the coordinate point along the y-axis.
a table of values can be created as shown below;
x h(x) = 3^x k(x) = 5^x 0 1 1 1 3 5 2 9 25 3 27 125
not shown on the graph are the values when x is negaive.
as the value of x becomes more negative, both equations will get closer to 0, but will never be equal to 0.
this is because 1 divided by any positive number can never be equal to 0, no matter how large that positive number is.
