I think there is a typo in the question. Is it f(26) = 3

You only have two points. You have no choice but to consider linear estimation.

Suppose that f is a function with f (25) = 61 and f^1 (25)= 3. If you have no further information, what is your best estimate of f(26.5)?

Ok you can integrate then.

that is the information we have. a point (25,f(25))

and the slope of a tangent line at that point

like we told you before, you can aproximate the value of the function with a straight line
