Nick's rectangular bedroom has a length of (2x−5) and a width of (x+1). Which equation describes the area, A, of Nick's bedroom
Mrac [35]

Answer:

A = 2x²-3x-5

Step-by-step explanation:

Given that,

The length of the bedroom, l = (2x-5)

Width of the bedroom, b = (x+1)

We need to find an equation for the area of the bedroom. We know that,

Area of a rectangle = lb

Put all the values,

A = (2x-5)(x+1)

= 2x²+2x-5x-5

= 2x²-3x-5

Hence, the area of the bedroom is equal to 2x²-3x-5.

Which of the following functions could be f(x) ?
notka56 [123]

Answer:

B.  f(x) = -x^3 - x^2 + 7x - 4

Step-by-step explanation:

For this problem, we want to find the fastest-growing term in our given expressions and equate them when x is - infinite and when x is infinite to see the given trends.

For each of these equations, we will simply take the terms with the highest power and consider those.  The two cases we need to consider is + infinite for x and - infinite for x.  Let's check each of these equations.

Note, any value raised to an even power will be positive.  Any negative value raised to an odd power will be negative.

<u>[A] - x^4</u>

<em>When x is +∞ --> - (∞)^4 -->  f(x) is -∞</em>

<em>When x is -∞ --> - (-∞)^4 --> f(x) is -∞</em>

<em />

<u>[B] - x^3</u>

<em>When x is +∞ --> - (∞)^3 --> f(x) is -∞</em>

<em>When x is -∞ --> - (-∞)^3 --> f(x) is ∞</em>

<em />

<u>[C] 2x^5</u>

<em>When x is +∞ --> 2(∞)^5 --> f(x) is ∞</em>

<em>When x is -∞ --> 2(-∞)^5 --> f(x) is -∞</em>

<em />

<u>[D] x^4</u>

<em>When x is +∞ --> (∞)^4 --> f(x) is ∞</em>

<em>When x is -∞ --> (-∞)^4 --> f(x) is ∞</em>

<em />

Notice how only option B, when looking at asymptotic (fastest-growing) values, satisfies the originally given conditions for the relation of x to f(x).

Cheers.
