Final answer:
To find the y-value of an exponential function given x = -2, substitute -2 for x in the equation and solve for y. This usually involves simplification and may require taking the natural logarithm. Without the explicit function, further calculation isn't possible.
Step-by-step explanation:
To determine the y-value when plugging in -2 for x into an exponential function, we would substitute -2 in place of x in the given equation and solve for y. Unfortunately, the provided excerpts do not include a complete expression for the exponential function; thus, we cannot solve it directly. However, we can discuss the procedure involved which includes the substitution of the given value into the function, simplifying the equation, and potentially using methods such as the natural logarithm (ln) to isolate y, especially if the equation involves an exponential term. If we had the complete function, after the substitution, we might need to employ a calculator for precise computation if the expression is beyond simple arithmetic.
Step-by-Step Procedure for Exponential Functions
Substitute the given x-value into the exponential function in place of x.
- Simplify the expression as much as possible.
- If the equation includes an exponent with x, consider taking the natural logarithm of both sides to solve for y.
Since an explicit equation was not provided, continuing with the calculation is not possible at this stage.
