Weegy: f(x) = 4^x is an exponential curve (I'm hoping you're familiar with these by now) which goes through (0, 1), (1, 4), (2, 16) going to the right of the y-axis. To the left of the y-axis, [ the curve approaches closer and closer to the x-axis without ever reaching it (so we have a horizontal asymptote y = 0). Domain: All real numbers. (There is no value x cannot be, because we can take a given number to any real number). Range: (0, infinity) Asymptote: y = 0. source: yahoo ] (More)

Weegy: The slope of the equation y = 0.15x+.79 is simply .15 (More)

Weegy: the two lines are intersecting lines. (More)
