Hi, I'm going over explanation of exercise 2 (see picture 1).

in step one of explanation (picture 2), it said that function is a root function and according to step 2, the function is f(x)=sq.root of x

How is it concluded that this function is a root function? Just by looking on the graph? But the graph does look like square root function.

thank you

The domain of f is D = {x x a constant function. This does Notice that f is constant on th 3.2 EXERCISES 1. The graph of a function f is shown. Verify that f satisfies the hypotheses of Rolle's Theorem on the interval [0, 8]. Then estimate the value(s) of c that satisfy the conclusion of Rolle's Theorem on that interval. y = f (x) 0 x 2. Draw the graph of a function defined on [0, 8] such that f(0) = f(8) = 3 and the function does not satisfy the conclusion of Rolle's Theorem on [0, 8].6:53 80 Step 1 of 6 Verify that f (x ) satisfies the conditions of the Mean Value Theorem. f (x) is a root function which is continuous on [0, 4] and differentiable on (0, 4). Step 2 of 6 Find f (4) and f(0). f ( 4) = V4 = 2 f(0) = Vo = 0 > Show me Step 3
