Step-by-step explanation:

let worth be y and age be x

y = k/x, where k is a constant, k ≠ 0

7000 = k/3

21000 = k

y = 21000/7

y = 3000

$3000

Evaluate the exponential function.
kakasveta [241]
Hey there!

Our function is:

f(x) = 4^x

If we want to have f(3), we simply can plug in 3 to our answer, and evalutate from there:

f(x) = 4^3 =
4*4*4 =
16*4 =
64

We just calculated 4 to the fourth power, which is four times four times four times four. Therefore, 4 of four is equal to 64.

Hope this helps!
