Q. If f′(x)=[f(x)]2 and f(0)=1, then f(6)=1/n for some integer n.What is n ?n=
Find f′(0): Since f′(x)=[f(x)]2 and f(0)=1, we can start by finding f′(0) using the given information.f′(0)=[f(0)]2=12=1.
Rate of Change at x=0: The derivative f′(x) represents the rate of change of f(x). Since f′(0)=1, the function f(x) is increasing at x=0.
Behavior of f(x): We know that f(x) is increasing and f(0)=1. If f′(x)=[f(x)]2, then f(x) must remain positive and increasing for all x > 0.
Integrate to find f(6): To find f(6), we need to integrate f′(x) from 0 to 6. However, we are given that f(6)=n1, so we need to find n that satisfies this condition.
Understanding f′(x): Since we don't have an explicit function for f(x), we cannot directly integrate f′(x). But we can use the fact that f′(x)=[f(x)]2 to understand the behavior of f(x).
Implications of f′(x): If f′(x)=[f(x)]2, then as x increases, f(x) will increase at a rate proportional to the square of f(x). This implies that f(x) will grow very quickly.
Determining n: Given that f(6)=n1, and knowing that f(x) grows quickly, n must be a very large number because f(6) is a very small positive number.
Determining n: Given that f(6)=n1, and knowing that f(x) grows quickly, n must be a very large number because f(6) is a very small positive number.However, without an explicit form for f(x), we cannot find the exact value of n. We need more information or a different approach to solve for n.
