Find the range of f(x) = -x2 + 1 for the domain {-2, 0, 2}

wariber [46]

Range is just input the domain

so find f(-2), f(0) and f(2)

f(-2)=-(-2)²+1=-4+1=-3
f(0)=-(0)²+1=0+1=1
f(2)=-(2)²+1=-4+1=-3

range={-3,1}

Chris wants to order blu-rays over the internet. Each Blu-ray cost $29.99 and shipping for

astra-53 [7]

Answer:

4 blu-rays

Step-by-step explanation:

*Note: I'm rounding up to full dollars to make this easier. You will get the same answer, whether you round up or not.

First, get rid of the shipping cost from the budget.

$150 - $10 = <u>$140 left for blu-rays</u>

Then divide $140 by $30, which is the price for a single blu-ray to get the number of blu-rays Chris can get.

$140 ÷ $30 ≈ 4.6 repeating. You can't have a fraction of a movie, so Chris can get 4 blu-rays

A small explanation would be really appreciated

shutvik [7]

Step-by-step explanation:

the 2 angles marked with orange and green are equal becos the question said that the indicated angles are congruent meaning same deg. so 180 - that given angle = the 2 marked angles (based on the rule known as angles on a str line are supplementary)

since the 2 marked angles are same, you can say that d and k are parallel due to the rule of alternate angles
