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

Andreyy89

Answer:

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.

Solve the system by the elimination method <br> 7x+5y=-25<br> 5x+3y=-23

aksik [14]

Step-by-step explanation:

7x+5y=25 ×3 7×-1.5+5y=25

5x+3y= -23 ×5 -10.5 +5y =25

5y= 25 + 10.5

21x+15y=75 5y= 35.5

25x+15y=69 y= 7.1

-4x=6

x=-1.5
