HELP PLEASE LOTS OF POINTS!!

Paladinen [302]

Answer:

Thus, f and g are inverse functions

Step-by-step explanation:

Inverse Functions

If two functions f(x) and g(x) are inverses, then it follows that:

$f\circ g(x)=x$

Or:

$g\circ f(x)=x$

We are given

$\displaystyle f(x)=\frac{1}{4}x-6$

$g(x)=4x+24$

Let's test if they are inverse functions:

$f\circ g(x)=\frac{1}{4}(4x+24)-6$

Simplifying:

$f\circ g(x)=x+6-6=x$

Now find:

$\displaystyle g\circ f(x)=4\left(\frac{1}{4}x-6\right)+24$

Operating:

$\displaystyle g\circ f(x)=x-24+24=x$

Thus, f and g are inverse functions

Samantha works at an animal shelter. She decides to track the total number of kittens that are brought in. The equation k=4w+3 r

mel-nik [20]

Answer:

Step-by-step explanation:

The equation $k=4w+3$ represents the total number of kittens, where $w$ represents the number of weeks that have passed since Samantha started counting.

This means options C and D are false, because they say the total number of kittens that have come into the shelter.

$w$ represents the number of weeks, weeks can be counted 0 weeks, first week, second week and so on, so option B is true (the domain is all whole numbers) because 0, 1, 2, 3, ... are whole numbers.

Number of weeks can't be a negative number. Since "real numbers" include negatives, therefore, we exclude option A.
