The given graph represents the function f(x) = 2(5)x. how will the appearance of the graph change if the a value in the function is decreased, but remains greater than 0? the graph will increase at a slower rate. the graph will show a decreasing, rather than increasing, function. the graph will show an initial value that is lower on the y-axis. the graph will increase at a constant additive rate, rather than a multiplicative rate.
