Math Problem Statement

Find sum of numeric values of inverse of a function f(x) = 2x+1

Solution

To find the sum of the numeric values of the inverse of the function f(x)=2x+1f(x) = 2x + 1, we first need to find the inverse function and then evaluate its numeric sum.

Step 1: Find the Inverse of f(x)f(x)

The function f(x)=2x+1f(x) = 2x + 1 is a linear function. To find the inverse, we follow these steps:

  1. Let y=f(x)y = f(x), so: y=2x+1y = 2x + 1

  2. Solve for xx in terms of yy: y1=2xy - 1 = 2x x=y12x = \frac{y - 1}{2}

  3. Now, replace yy with xx to get the inverse function: f1(x)=x12f^{-1}(x) = \frac{x - 1}{2}

Step 2: Sum of Numeric Values of the Inverse

The problem asks for the sum of numeric values of the inverse function. This is a bit ambiguous because there are infinite values for xx, so the sum would be unbounded. However, if you're asking for the sum of a particular set of numeric values for the inverse, we would need to specify a set of inputs (e.g., values of xx) to calculate the sum of their corresponding values under the inverse function.

If you want to find the sum of specific values of the inverse function (say for x=1,2,3,x = 1, 2, 3, \dots), please clarify which values you're referring to.

Would you like to proceed with a specific set of xx-values for the inverse function, or do you need further clarification? Let me know!

Tip:

Remember, when finding the inverse of a function, always check if the function is one-to-one (injective). If a function is not one-to-one, it will not have an inverse that is also a function.
