Fill in the blank spaces please.
Kisachek [45]

<u><em>PART A</em></u>

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

<u>So for 2 pounds, it would cost </u><u>$5.00</u>

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

<u>For the 1 pound one, it would cost </u><u>$2.50</u>

<u></u>

<u><em>PART B</em></u>

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, <u>$1 = 0.4lb</u>

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x <u>$9 = 3.6lb</u>

<u></u>

To one-one functions g and h are defined as follows.
Andreyy89

Answer:

  • 9
  • (x-8)/3
  • -1

Step-by-step explanation:

The inverse function for a set of ordered pairs can be found by swapping the x- and y-coordinates in each pair.

  g^{-1}(-1)=9\qquad\text{from the $g(x)$ ordered pair $(9, -1)$}

__

The inverse of a function expressed algebraically can be found by swapping the x- and y-variables and solving for y.

  h^{-1}(x)\qquad\text{is found from }x=h(y)\\\\x=3y+8\\x-8=3y\\\\y=\dfrac{x-8}{3}\\\\\boxed{h^{-1}(x)=\dfrac{x-8}{3}}

A function of its own inverse returns the original value:

  \boxed{\left(h\circ h^{-1}\right)(-1)=-1}
