Solve f (x) = 32^x+6•1/2 = 8^x-1

Option B: The value of x is -16

Explanation:

Given that the equation

We need to determine the value of x.

Let us substitute f(x) = 0, then we have,

Now, we shall determine the value of x.

The term can be written as

Hence, we have,

Also, the term can be written as

Thus, we have,

Applying the exponent rule, , we have,

If then

Simplifying, we get,

Therefore, the value of x is -16

Hence, Option B is the correct answer.
