# For each of the following exponential functions: (I) Graph the function, including the asymptote. Use good graphing practices.

For each of the following exponential functions: (I) Graph the function, including the asymptote. Use good graphing practices. (II) Write the domain and range for each function using interval notation

1. y = 3x
2. y=3x+1-2
3. y= - 2(3)x+4
4. y=1/2(x)x-3

Consider the following exponential function, in which A through C are positive real constants. f(x) = A(B)x + C Explain in words how you would ﬁnd each of the graph characteristics below, then proceed to ﬁnd them. For each explanation, include some justiﬁcation of your method (that is, "Why does it work?").

(a) Domain

(b) Range

(c) Horizontal asymptote

(d) y-intercept
