Question

Which of the following is a function equivalent to f(x) = 4(1.8)2x?

f(x) = 4(3.24)x

f(x) = 4(3.24x)

f(x) = 12.96x

f(x) = 51.84x

Answer 1

A

Explanation:

1.8 times 1.8 equals= 3.24

Answer 2

If you would like to know which is a function equivalent to f(x) = 4 * (1.8)^(2x), you can calculate this using the following steps:

f(x) = 4 * (1.8)^(2x)
f(x) = 4 * 3.24^x
f(x) = 4 * (3.24)^x

The correct result would be f(x) = 4(3.24)x.
