What is the range of (w*r)(x)

Natasha_Volkova [10]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

$r(x)=2-x^2\\\\w(x)=x-2$

we need to find the composition of function w and r i.e.

$w\circ r=w(r(x))=w(2-x^2)=2-x^2-2=-x^2$

Since the range of $-x^2$ must be $(-\infty,0}$ .

As its values can be any negative real number in this interval.

Hence, first option is correct.

Mushrooms are healthy food for wild songbirds. Adam buys a 3.5 oz container of mealworms for $8.75. Marco buys a 3.75- oz contai

Lady bird [3.3K]

Answer:

Adam's container

Step-by-step explanation:

Given

Adam

$Weight = 3.5\ oz$

$Amount = \$8.75$

Macro

$Weight = 3.75\ oz$

$Amount = \$9.75$

Required

Determine the better buy

First, we need to determine the unit cost per oz of each

i.e.

$Unit\ Cost = \frac{Amount}{Weight}$

For Adam:

$Unit\ Cost = \frac{8.75}{3.5}$

$Unit\ Cost = 2.5$

For Marco:

$Unit\ Cost = \frac{9.75}{3.75}$

$Unit\ Cost = 2.6$

The better buy of both is the one with the smaller unit cost.

<em>Since 2.5 < 2.6, we can conclude that Adam's container is a better buy</em>
