Find f(-2) for f(x)=2(4)^x

lesya692 [45]

For this case we have the following exponential function:
$f (x) = 2 (4) ^ x
$
To find the value of f (-2) what we must do is substitute the value of x = -2 in the given function.
We have then:
$f (x) = 2 (4) ^{-2}$
Then, rewriting the function we have:
$f (x) = \frac{2}{4^2}$
$f (x) = \frac{2}{16}$
Finally, simplifying we have:
$f (x) = \frac{1}{8}$
Answer:
The value of f (-2) is:
$f (x) = \frac{1}{8}$
