Question

Which of the following options is an equivalent function to f(x) = 2(5)2x?

f(x) = 50x
f(x) = 100x
f(x) = 2(25)x
f(x) = 4(25)x
help please

Answer 1

please help

Answer 2

The way you typed it, none of them
Perhaps you mean
f(x) = 2 * (5)^2 * x
= 2 * 25 * x
= 50 x
but 2(25) x also works

Answer 3

I think you want 2*5^(2x) = 2*(5^2)^x = 2*25^x
