Mr. Wallace writes a function on the board, where y represents the total amount of money in a bank account after x years. y = 2(105)^x What is the domain of the function?
a) all integers
b) all positive integers
c) all positive real integers
d) all real numbers

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

32

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
