The answer is [3,4].
Given:
the values of two functions f(x) and g(x) given corresponding to different values of x.
Find:
we have to find the interval for which f(x) can be equal to g(x).
Step-by-step explanation:
As the range of f(x) for domain [3,4] is [0.68,0.86]
and the range of g(x) for domain [3,4] is [0,1],
So, it is clear that there exist a point in domain [3,4] at which f(x) = g(x).
