Calculate with a given accuracy the initial value of the first interval of continuous non-decreasing function?

Question

Mathematics

1. Calculate with a given accuracy the initial value of the first interval of a continuous non-decreasing function on (a, c)
2. Calculate the final value of the first interval of a continuous non-decreasing function on (a, c)
what does "the initial value of the first interval of a continuous non-decreasing function" mean? and "final value of the first interval of continuous non-decreasing function?"

Answer 1

What is non-decreasing function, you know?
What is a function interval, do you know?
The initial one is probably closer to the origin of coordinates (points O), the final one is towards the end, the numbering of intervals (first, second ...) is probably on the same principle.
And the value of the interval - probably means the value of the function, that is, yat this point.
