Can somebody please help my with this question

ki77a [65]

Answer:

All the possible values of $a-b$ lies in the interval $3$ .

Step-by-step explanation:

As the range of $a$ is

$3$

As the range of $b$ is

$4$

As $a$ contains the set of number between 3 to 4, and $b$ contains the values of from 4 to 5.

$a-b$ can be obtained by subtracting the values of $b$ from $a$ .

So,

$a-b$

⇒ $(3$

⇒ $3$

Therefore, all the possible values of $a-b$ lies in the interval $3$ .

Complete the sentences to describe the function f(x) = 2x^2+16x/16x^3-x the function is discontinus at

wel

Answer:

The answer is " $\bold{\frac{2(x+8)}{(4x^2- 1)(4x^2+ 1)}}$ ".

Step-by-step explanation:

$\to f(x) = \frac{2x^2+16x}{16x^3-x}$

$= \frac{2x(x+8)}{x(16x^2-1)}\\\\= \frac{2(x+8)}{(16x^2-1)}\\\\= \frac{2(x+8)}{((4x)^2-(1)^2)}\\\\= \frac{2(x+8)}{(4x^2- 1)(4x^2+ 1)}\\\\$
