On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. it goes through (negative 2, 2) and crosses the y-axis at (0, 3). consider the exponential function: f(x) = 3(five-fourths) superscript x the initial value for this function is . the base for this function is . the domain for this function is . the range for this function is .
