Without the image, I can't directly identify the x-value of the relative maximum on the graph of \( f(x) \). However, to determine the x-value of a relative maximum from a given curve:
- Look for peaks in the S-shaped curve where the function changes from increasing to decreasing.
- The x-coordinate where this peak occurs represents the x-value of the relative maximum.
Please refer to the graph you have to find the indicated point of maximum.
