Let f be a continuous function defined on the interval [0,1] such that f(0) = f(1). Show that there exists a number 0 <= a &l
Leni [432]

Explanation:

In order to prove that affirmation, we define the function g over the interval [0, 1/2] with the formula g(x) = f(x+1/2)-f(x) .

If we evaluate g at the  endpoints we have

g(0) = f(1/2)-f(0) = f(1/2) - f(1) (because f(0) = f(1))  

g(1/2) = f(1) - f(1/2) = -g(0)

Since g(1/2) = -g(0), we have one chance out of three

  • g(0) > 0 and g(1/2) < 0
  • g(0) < 0 and g(1/2) > 0
  • g(0) = g(1/2) = 0

We will prove that g has a zero on [0,1/2]. If g(0) = 0, then it is trivial. If g(0) ≠ 0, then we are in one of the first two cases, and therefore g(0) * g(1/2) < 0. Since f is continuous, so is g. Bolzano's Theorem assures that there exists c in (0,1/2) such that g(c) = 0.  This proves that g has at least one zero on [0,1/2].

Let c be a 0 of g, then we have

0 = g(c) = f(c+1/2)-f(c)

Hence, f(c+1/2) = f(c) as we wanted.

(Will give Brainliest) Explain what the graph of the function represents. Be sure to use complete sentences.
Irina-Kira [14]

Answer: f(-735) = -\frac{2}{3}(-735) + 490 = 980

Step-by-step explanation:

f(x) = -\frac{2}{3} x + 490 =0  Subtract 490 from both sides

        \frac{3}{2}* -\frac{2}{3} x = -490 *\frac{3}{2}   Then flip -\frac{2}{3} multiply both sides by \frac{3}{2} to cancel out -\frac{2}{3}

      x= -735  Thus giving you -735 as your x.

Then you plug it back into the equation to solve.
