What is the domain and range of f (x) = 3 (4) ^x

Step-by-step explanation:

Find the y-intercept by setting x = 0: f (0) = 3 (4) ^0 = 3 (1) = 3 = > (0, 3)

4^x is never zero, and its graph is always above the y-axis, for both positive and negative x.

Any real number is an acceptable x-value.

Thus the domain is ( - infinity, infinity) and the range is (0, infinity).
