Question

Which of the following options is an equivalent function to f(x) = 4(3)2x?
f(x) = 36x
f(x) = 4(9)x
f(x) = 144x
f(x) = 4(6x)

Answer 1

Multiply out all the coefficients of the original function. 4*3*2 equates to 24. Therefore, find the function that has a coefficient multiplicative expression that equates to 24. The term 4(6) seems awfully close to 24 as does 4(3)(2), in my opinion! ;)
