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
a. 0
b. 1
c. 5\4

The base for this function is
a. 0
b. 1
c. 5\4
d. 3
The domain for this function is
a. y>0
b. y<0
c. all real numbers
d. y=0
