Given the equation xy+4y=3x-2 show that y is a function of x and determine the domain in interval notation.

1 answer:

7 0

First, the equation has to be rearranged so that y will be isolated on the left-hand side of the equation.

(x + 4)y = 3x - 2y = (3x - 2)/(x + 4)

This form is a rational function which is of course a function. All values of x are possible, except for x when y becomes undefined, thus the domain should be x /= -4. In interval notation, (-inf, -4) U (-4, inf).

Step-by-step explanation:

Hello!

Statements:

Which statement correctly compares the spreads of the distributions?

a. the mode of penguin heights at county side zoo is greater than the mode at city view zoo.

b. the ranges of penguin heights are the same.

c. the range of penguin heights is greater at city view zoo than at county side zoo.

d. the range of penguin heights is greater at county side zoo than at city view zoo.

The mode and mean are measurements of central tendency, these indicate the position of a data set but don't show any information concerning the distribution of said data.

The range on the other had is a measurement of variance, it shows the difference between the maximum and minimum values of the data set and indicates its total dispersion.

City view Zoo R= 44-37= 7 cm

County side Zoo: R= 45-38= 7 cm

Both ranges are the same.

I hope this helps!
