Identify the type of function represented by f(x) = 4•(1/3)^x

Mathematics
1 answer:
aliina [53]4 years ago
6 0

Answer:

C

Step-by-step explanation:

By looking at the exponent you can immediately tell the function is an exponential one. However, to further determine if it's positive or negative you need to look at the base of the exponent. If the base is above 1 the function is positive, while on the other hand if it is smaller than 1 it is negative. In this case the base is 1/3 which is equal to .33, so this function is an exponential decay.

What is the product of (x − 3) and (x + 7)?
NeX [460]

Answer:

The product of (x-3) and (x+7) is x² + 4x - 21

Step-by-step explanation:

The product of (x-3) and (x+7) is x² + 4x - 21

The product of (x - 3) and (x + 7) can be found as follows:

(x - 3)(x + 7)

open the bracket by multiplying

Therefore,

x(x) +x(7) - 3(x) - 3(7)

x² + 7x - 3x - 21

combine like terms

x² + 4x - 21

I don’t know how to do that
Alisiya [41]

Answer:

16

Step-by-step explanation:

Divide 64 by 8 to get 8. this is 1/8 of the books.

3/8 were non fiction, or 24

1/4 (2/8) were picture books, or 16

5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.

3/8 were chapter books, or 24.

add the amount of picture books and chapter books since they are the fictional texts.

16+24=40

subtract the amount of non fictional books from the amount of fictional books to get the sum.

40-24=16
