Use the definition of continuity and the properties of limit to show that the function f(x)=x sqrtx/ (x-6)^2 is continuous at x=
jasenka [17]

Answer:

The function \\ f(x) = \frac{x*\sqrt{x}}{(x-6)^{2}} is continuous at x = 36.

Step-by-step explanation:

We need to follow the following steps:

The function is:

\\ f(x) = \frac{x*\sqrt{x}}{(x-6)^{2}}

The function is continuous at point x=36 if:

  1. The function \\ f(x) exists at x=36.
  2. The limit on both sides of 36 exists.
  3. The value of the function at x=36 is the same as the value of the limit of the function at x = 36.

Therefore:

The value of the function at x = 36 is:

\\ f(36) = \frac{36*\sqrt{36}}{(36-6)^{2}}

\\ f(36) = \frac{36*6}{900} = \frac{6}{25}

The limit of the \\ f(x) is the same at both sides of x=36, that is, the evaluation of the limit for values coming below x = 36, or 33, 34, 35.5, 35.9, 35.99999 is the same that the limit for values coming above x = 36, or 38, 37, 36.5, 36.1, 36.01, 36.001, 36.0001, etc.

For this case:

\\ lim_{x \to 36} f(x) = \frac{x*\sqrt{x}}{(x-6)^{2}}

\\ \lim_{x \to 36} f(x) = \frac{6}{25}

Since

\\ f(36) = \frac{6}{25}

And

\\ \lim_{x \to 36} f(x) = \frac{6}{25}

Then, the function \\ f(x) = \frac{x*\sqrt{x}}{(x-6)^{2}} is continuous at x = 36.

Multiple choice questions .
Arlecino [84]

Answer:

<h3>          1. a), </h3><h3>          2. c), </h3><h3>          3. b), </h3><h3>          4. a), </h3><h3>          5. a), </h3><h3>          6. c), </h3><h3>          7. ⁵/₃ or 5÷3 or 1 ²/₃</h3>

Step-by-step explanation:

1. 0 divided by any number is always 0

2.  7×(5-5) = 7×0 = 0

3. Integers between -5 and 5 are:

  -4, -3, -2, -1, 0, 1, 2, 3 and 4

4.  - ( |5 - 11| ) = - ( |-6| ) = - ( 6 ) = -6

5. Numerical coefficient is the number with its sign. No letters.

6. x increased by y means: y more than x. And x+y = y+x

7. one third of 5 means  \frac13\cdot5 so it is: \frac53=5:3=1\frac23
