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).

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
