Answer:

y = -|x - 2| + 4

Step-by-step explanation:

The parent function of the absolute value function is y = |x|. There is a negative reflection in the x-axis, a horizontal translation of 2 units right, and a vertical translation of 4 units up.

The O'Brien's are building a rectangular deck around the outside of their circular pool.

Lera25 [3.4K]

Width of the deck = $2x+3$ units

Length of the deck = $5x+6$ units

So area of rectangular deck = Length * width

= $(5x+6)(2x+3)$

Area = $10x^{2}+15x+12x+18$

Area= $10x^{2}+27x+18$ units square

As mentioned in part B, the area of the pool is $3x^{2}+7x+6$ so the combined area of the deck and pool is

Area = area of rectangular deck + area of pool

= $13x^{2}+34x+24$ unit square

The area of only the deck is $10x^{2}+27x+18$ unit square

Answer:

Value of $f^{-1}(\{4\})$ is 8.

Step-by-step explanation:

Given function,

$f(x)=\big[\frac{x}{2}\big]$

we have to find : $f^{-1}(\{4\})$

It is known that,

$[x]$ =the greatest integer <=x

Then,

$f(x)=\big[\frac{x}{2}\big]$

$\implies x=f^{-1}(\big[\frac{x}{2}\big])$

Taking x=8 we get,

$f^{-1}(\big[\frac{x}{2}\big])=x$

$\implies f^{-1}(\big[\frac{8}{2}\big])=8$

$\implies f^{-1}([4])=8$

$\implies f^{-1}(\{4\})=8$ ( Since [4]=4 )

Hence the value of $f^{-1}(\{4\})$ is 8.
