Answer:

B. f(x) = (x − 1)(x − 2)(x + 1)(x + 2)

Step-by-step explanation:

Choice A will be a transformation of the function f(x) = x³.  The parent function goes from the third quadrant through the origin into the first quadrant.  This is not a cubic function.

Choice C will be a transformation of the function f(x) = x⁵.  The parent function goes from the third quadrant through the origin into the first quadrant.  This is not one of those functions.

Choice D will be a transformation of the function f(x) = x³.  This is not a cubic function.

Choice D will be a transformation of the function f(x) = x⁴.  These functions go from the second quadrant across the y-axis into the first quadrant.  This is a quartic function.

A violin was on sale of 50%
irinina [24]
If it is 50% then it should be half of the original price.

For Example: $30.00 - 50%... the answer would be $15.00 since its the half of the $30.00

How do you identify the information that is given to you that you dont need for solving a problem?
Alborosie
When reading a question, you need to be aware of the numbers presented and the facts. You need to pay attention to the question - what, when, where, how, why or how much. What is being asked in the question is always your clue. Unnecessary information will be eliminated once you understand the question.

Simple example from a Business book:

Jessica Fernandez, manager of Subway, had a bank balance of $5382.12 on March 1. During March, she deposited $60,375.82 received from sales, $3280.18 received as credits from suppliers, and $75.53 as a county tax refund. She paid out $27,282.75 to suppliers, $4280.83 for rent and utilities, and $12,252.23 for salaries and miscellaneous. How much did Fernandez deposit in March?

Answer:
$60,375.82 (sales) + $3280.18 (credits) + $75.53 (refund) = $63,731.53
Fernandez deposit $63,731.53 in March.

The question immediately lead you to the sentence that is the key to the answer.
It is pretty obvious but try to recognize the important facts from the rest.
The question did not ask about Jessica's balance on March 1 or did not ask about how much she pay out. You can immediately eliminate that those information are not necessary to the problem being asked. The question is how much did she deposit in March. You need to find the sentence that points out the answer - During March, she deposited $60,375.82 received from sales, $3280.18 received as credits from suppliers, and $75.53 as a county tax refund. List all the numbers and add them together and you will come up with the figures she deposited. It is just a simple question but it presented the technique for the elimination process of unnecessary facts. It is not "we cannot see the answer" but the truth is we cannot see and understand the question.

Please can someone answer this.
ivanzaharov [21]

Answer:

  •  x = -4, x = 0, x = 1

Step-by-step explanation:

x is a factor of all terms, so x=0 is a zero. (Eliminates choices 1 and 5.)

The sum of coefficients is 0, so x=1 is a zero. (Eliminates choices 3 and 4.)

Reversing the sign of the odd-degree terms gives signs of -++, so there is one sign change, hence one negative real root (by Descartes' rule of signs). This confirms choice 2 as the answer.

___

Of course, your graphing calculator can answer this almost as quickly.
