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.

Answer:

<h2>z = 6</h2>

Step-by-step explanation:

4(z+1)=2(z-1)+18\qquad\text{use the distributive property}\\\\(4)(z)+(4)(1)=(2)(z)+(2)(-1)+18\\\\4z+4=2z-2+18\qquad\text{subtract 4 and}\ 2z\ \text{from both sides}\\\\4z-2z+4-4=2z-2z-2+18-4\qquad\text{combine like terms}\\\\2z=12\qquad\text{divide both sides by 2}\\\\z=6

An arithmetic sequence follows a specific pattern where a number is _____________ to get from one term to the next.
Nikitich [7]

Answer:

Added

Step-by-step explanation:

For example, take the arithmetic sequence of 3, 5, 7, 9...

Here, the number that gets us from the first number to the second (from 3 to 5), is 2. Meaning, we need to add 2 to 3 in order to get 5. I believe that makes "addition" or "added" the answer. Please let me know if I misunderstood and I will change my answer! Thank you!
