Use a table of numerical values of f(x,y) for (x,y) near the origin to make a conjecture about the value of the limit of f(x,y)
grigory [225]
Seems to be that the limit to compute is

\displaystyle\lim_{(x,y)\to(0,0)}\frac{xy}{x^2+2y^2}

Consider an arbitrary line through the origin y=mx, so that we rewrite the above as

\displaystyle\lim_{x\to0}\frac{mx^2}{x^2+2m^2x^2}=\lim_{x\to0}\frac m{1+2m^2}=\frac m{1+2m^2}

The value of the limit then depends on the slope m of the line chosen, which means the limit is path-dependent and thus does not exist.

The scatter plot shows the number of text messages sent per day versus age (in years) of the smartphone user.
Ghella [55]

Answer: find the answers in the explanation.

Step-by-step explanation:

Given that the predicted Number of Text Messages Sent = 60 – 0.8 • Age

Where the slope = - 0.8

The intercept = 60

1) the slope of the least regression line is -0.8

2.) The unit of the slope of the line is text per year

3.) Therefore, the slope of the line tells you that for every year older the smart phone user is, you can expect a typical average in text messages sent of - 0.8

4.) The y - intercept of the least square regression line is 60

5.) The unit of the y - intercept of the line are text sent

6.) The y - intercept of the line tells you the starting point. The first number of text messages sent.
