First of all, let's rewrite the expression in function form.
The original equation is:
-10 * (1/2)^x = 1
We can define a function from the left-hand side of the equation:
f(x) = -10 * (1/2)^x
This is the function form. The original equation is now written as:
f(x) = 1
This means we are looking for the value of x where the function equals 1.
