Final answer:
Given the function f(x) = x/8, substituting x with 10 gives f(10) = 10/8, which simplifies to 1.25.
Step-by-step explanation:
To find the value of f(x) when x = 10, given that f(x) = startfraction x over 2 endfraction 8, it appears there might be a typo or mistake in the function's expression. However, if we assume the intended function is f(x) = x/8, we can substitute x with 10 and calculate as follows:
f(10) = 10/8
To simplify, we divide the numerator and the denominator by their greatest common divisor, which is 2. This gives us:
f(10) = 5/4
When expressed as a decimal, 5/4 is equivalent to 1.25.
