Answer:

Option A

Step-by-step explanation:

The domain of a function is the set of all numbers that has an image in the co domain. It means that those elements are mapped to other elements and give output values.

From the figure we see that all the elements in $x$ are marked to other elements in $f(x)$ . So, the domain would be:

$\{-4, -1, 0, 2, 7\}$

Hence, Option A.

A high rise apartment building has 15 floors with 26 apartments on each floor.There are 3 kinds of apartments in the building: 1

konstantin123 [22]

Answer:

The number of each kind of apartment in the building is 130 .

Step-by-step explanation:

Given as :

The total number of floor in a building = 15

The number of apartment on each floor = 26

So, The total number of apartment = 26 × 15 = 390

The number of kinds of apartment in the building is 3 , i.e 1-bedroom , 2-bedroom , 3-bedroom

Let The number of each kind of apartment in building = x

So, According to question

The number of each kind of building = $\dfrac{\textrm Total number of apartment }{number of kinds of apartment}$

or, x = $\frac{390}{3}$

∴ x = 130

Hence The number of each kind of apartment in the building is 130 . Answer

Evaluate the function fx = 4 * 7^t for x= -1 and x=2

Alex73 [517]

Well what i think you're asking here...I apologie if I'm wrong but what I did was

f(-1) = 4 * 7^t = 4/7

and

f(2) = 4 * 7^t = 196.

Is this what you wanted if not I can...try another way.
