B. It is vertically stretched by a factor of 4. If you had x^2 versus 4x^2, when x is positive and increasing, 4x^2 is increased by 4 for every value of x.

Find the error in the problem below

qaws [65]

Answer:

You aren't supposed to add 3k

Step-by-step explanation:

3k is a positve number. So instead of adding you have to subtract to be able to move on. Correct way shown below. Once you get this step wrong your answer will also be wrong. At the end you also need to divide

19-2k= 3k-1

-3k -3k

19-5k= -1

-19 -19

-5k= -20

-5/-5= -20/-5

k=4

Estimate the limit.

Bezzdna [24]

Answer:

a. 0.25

Step-by-step explanation:

The given expression is

$\lim_{x \to 2} \frac{x-2}{x^2-4}$

Factor the denominator using difference of two squares.

$\lim_{x \to 2} \frac{x-2}{(x-2)(x+2)}$

Cancel out common factors;

$\lim_{x \to 2} \frac{1}{(x+2)}$

We plug in 2 to get

$\lim_{x \to 2} \frac{1}{(x+2)}=\frac{1}{2+2}$

$\lim_{x \to 2} \frac{1}{(x+2)}=\frac{1}{4}=0.25$
