14. f(x) = -x4 + x² + 4; x = -1

Mathematics
1 answer:

Answer:

  f(-1) = 4

Step-by-step explanation:

See below for the synthetic division tableau. The remainder is 4, hence ...

  f(-1) = 4

___

IMO, in this function it is far easier just to substitute -1 for x. Since the only terms are of even degree, the value of f(-1) is the sum of the coefficients:

  f(-1) = -1 +1 +4

  f(-1) = 4

What is the net change in how many bags are on the shelf from
Temka [501]

Answer:

-2

Step-by-step explanation:

The computation of net change from the beginning of Tuesday to the end of Monday is shown below:-

The change at the last of Tuesday

Change = Restock - Sales

= 6 - 5

= 1

Here it indicates that the number of bags is rise by 1

The change at the last of Wednesday

Change = Restock - Sales

= 12 - 8

= 4

Here it indicates that the number of bags is rise by 4

The change at the last of Thursday

Change = Restock - Sales

= 12 - 2

= 10

Here it indicates that the number of bags is rise by 10

The change at the last of Friday

Change = Restock - Sales

= 18 - 19

= -1

Here it indicates that the number of bags is fall by -1

The change at the last of Saturday

Change = Restock - Sales

= 24 - 22

= 2

Here it indicates that the number of bags is rise by 2

The change at the last of Sunday

Change = Restock - Sales

= 0 - 15

= -15

Here it indicates that the number of bags is fall by -15

The change at the last of Monday

Change = Restock - Sales

= 0 - 3

= -3

Here it indicates that the number of bags is fall by -3

According to the given situation, it is equivalent the algebraic sum of every change

So,

Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)

Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)

Simplifying: 17 - 19 = -2

Write the inverse of f(x)=x2+4
Over [174]
F(x) = x² + 4
y = x² + 4

First, I reverse the equation to be
x² + 4 = y

Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)

Last, change into invers function
f⁻¹(x) = √(x - 4)
