The correct match will be closest to zero = x-y , greatest value = x + y and least value = -x

<h3>What is graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The vertical line is representing the data from 0 to 8 positive side and 0 to -8 negative side. We can see that the closest value to zero will be x-y

the least value will be -x and the greatest value is x + y.

Each interval is of unit 2 so the values x and y will be 4 and 2 respectively

closest to zero = x-y = 4-2 = 2

greatest value = x + y = 4+2 = 6

least value = -x = -4

Therefore the correct match will be closest to zero = x-y , greatest value = x + y and least value = -x

Let f and g be the functions defined by f(x) = 10^ (x+2 / 3) and g(x) = log (x3 / 100) for all positive real numbers,

Vaselesa [24]

Answer:

F(x) and g(x) are not inverse functions.

Step-by-step explanation:

In order to calculate the inverse function of a function, we have to isolate X and after that, we change the variables.

As our function f(x) is a exponentian function, we can apply logarithm with base 10 (log) in both sides in order to isolate X. Remember that log10=1.

$[tex]y=10^{(x+\frac{2}{3}) }\\\\log y=log 10^{(x+\frac{2}{3}) }\\log y = (x+\frac{2}{3}) . log10\\\frac{log Y}{log10} = (x+\frac{2}{3})\\\frac{log Y}{1} = (x+\frac{2}{3})\\log Y-\frac{2}{3}=x$ [/tex]

Now we change the variables.

$F(x)=log x-\frac{2}{3}$

F(x) and g(x) are not inverse functions.

It takes 40 minutes for eight people to paint four walls how many minutes does it takes 10 people to paint seven walls

sasho [114]

8r(40)=4

r=1/80 that is the rate for each person...

10rt=7 using r we found before

10(1/80)t=7

t/8=7

t=56 minutes.

Answer:

3, 0, -5, -6

Step-by-step explanation:

when x= -8, f(x) = 8-5 or 3

when x= -5 f(x) = 5-5 or 0

when x= 0, f(x) = 0-5 or -5

when x=1, f(x) = -1-5 or -6
