Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

3 + 6x + -8x = -14 + 8x + -8x

Combine like terms: 6x + -8x = -2x

3 + -2x = -14 + 8x + -8x

Combine like terms: 8x + -8x = 0

3 + -2x = -14 + 0

3 + -2x = -14

Add '-3' to each side of the equation.

3 + -3 + -2x = -14 + -3

Combine like terms: 3 + -3 = 0

0 + -2x = -14 + -3

-2x = -14 + -3

Combine like terms: -14 + -3 = -17

-2x = -17

Divide each side by '-2'.

x = 8.5

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:
$f (x) = \frac{1}{8}$
option B
