Find the absolute maximum value for the function f(x) = x^2 − 4, on the interval [–3, 0) U (0, 2].

Andreyy89

Answer:

5

Step-by-step explanation:

The function $y=x^2 -4$ is

decreasing for all $x\in [-3,0);$
is increasing for all $x\in (0,2]$

(see attached diagram for details).

The maximum value of the function is at endpoints -3 or 2. find y(-3) and y(2):

$y(-3)=(-3)^2-4=9-4=5\\ \\y(2)=4^2-4=0$

So, the maximum value is 5.

Ed needed to extend the string on his kite. The current string was eight and three fourths feet. He cut a piece of string that m

Pani-rosa [81]

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top)

<h3> What is the new length of the string?</h3>

We know that the current string was (8 + 3/4) feet in length. Then they add another piece that measures 4.5 feet.

The new length of the string is given by the addition of the above two lengths, we will get:

L = (8 + 3/4) feet + 4.5 feet

We can rewrite the second length as a mixed number:

4.5 = 4 + 1/2 = 4 + 2/4

Replacing that we get:

L = (8 + 3/4) ft + 4.5 ft

= (8 + 3/4) ft + (4 + 2/4) ft

= (8 + 4) ft + (3/4 + 2/4) ft

= 12ft + 5/4ft = 12ft + (4/4 + 1/4)ft = (13 + 1/4)ft

The new length of the string is (13 + 1/4) feet, then the correct option is the last one (counting from the top).

An item is called "price elastic" if you drop the price and revenue goes up. Last week you sold 10 sodas for $2 each; this week

aleksandrvk [35]

The soda is price elastic because if you sell 10 dollars ecah you have an revenue of 20 dollars. And if you shorten the price to 1 dollar and you sell 30 of them you have a revenue of 30 dollars.
So the sodas are price elastic.

Which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring? −b, b2 − 4ac, 2a Use th

denpristay [2]

<span>The expression b^2-4ac is called the discriminant. If it is zero, or positive and a perfect square (like 4, 9, 25, 36, etc), the solutions to the quadratic equation will be rational numbers and factoring will work.

On the other hand, if the discriminant is positive but not a perfect square, the solutions will be irrational, and if it is negative, there are no real solutions. In either of those cases, the quadratic expression cannot be factored.

In the equation 2x^2+7x+3=0, the discriminant is b^2-4ac = 7^2 - 4*2*3= 49-24 = 25 = 5^2

That means that the solutions can be found by factoring.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span>
