The end behavior of the function y = x² is given as follows:

f(x) -> ∞ as x -> - ∞; f(x) -> ∞ as x -> - ∞.

<h3>How to identify the end behavior of a function?</h3>

The end behavior of a function is given by the limit of f(x) when x goes to both negative and positive infinity.

In this problem, the function is:

y = x².

When x goes to negative infinity, the limit is:

lim x -> - ∞ f(x) = (-∞)² = ∞.

Meaning that the function is increasing at the left corner of it's graph.

When x goes to positive infinity, the limit is:

lim x -> ∞ f(x) = (∞)² = ∞.

Meaning that the function is also increasing at the right corner of it's graph.

Thus the last option is the correct option regarding the end behavior of the function.

<h3>Missing information</h3>

We suppose that the function is y = x².

Answer:

The value of x is -2 and 2.

Step-by-step explanation:

When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :

x² - 3x - 1 = -3x + 3

x² - 3x - 1 + 3x - 3 = 0

x² - 4 = 0

Next, you have to factorize and solve it :

x² - 4 = 0

x² + 2x - 2x - 4 = 0

x(x + 2) - 2(x + 2) = 0

(x + 2)(x - 2) = 0

x + 2 = 0

x = -2

x - 2 = 0

x = 2

Scilla [17]

Answer:Store A

Step-by-step explanation:

Given

Store A sells 3 cells phones that cost $165 each and offer 4 th one free

i.e. Effective cost of each cell phone is  \frac{165\times 3}{4}=\$ 123.75

Store B sells each cell phone at \$ 135 each

clearly, store A provides a better deal than B because the cost of 4 cell phones is less for Store A i.e.

\Rightarrow 165\times3
