I need help with: the graph of f(x)=(1/2)^x is either an increasing or decreasing function with a y-intercept of either (0,1), or (0, 1/2). i think its increasing but not sure on the intercept.

\n" ); document.write( "It's decreasing 1/2 * 1/2 * 1/2 would get smaller and smaller, right?
\n" ); document.write( ":
\n" ); document.write( "When the exponent = 0, the value is always 1, y intercept occurs when x = 0
\n" ); document.write( "you have (1/2)^0 which equals 1
