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

Is your equation actually \(\sf\Large f(x) = 4(3)^{2x}\)

Or is it
\(\sf\Large f(x) = 4(3)(2x)\)

Answer 2

its the first one

Answer 3

@TheSmartOne please help me

Answer 4

ok, so we can say that x + x = 2x

right?

Answer 5

yes

Answer 6

and do you know this property \(\sf\Large a^b \times a^b = a^{b+b}\)

Answer 7

kind of

Answer 8

do you know the property:

\(\sf\Large (a^b)^c = a^{bc}\)

Answer 9

ok, good, we're going to use it :)

Answer 10

\(\sf\Large f(x) = (4)(3^{2x}) = (4)(3^2)^x\)

What is 3^2 = 3 x 3 = ?
