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.

Find the slope of the line y= -4x - 2/3
IrinaVladis [17]

Hi there!

The general equation of a slope-intercept line is :

y = mx + b

Where "m" is the slope and "b" is the y-intercept.

Since your equation is already in the right form, you can easily see that your "m" is equal to -4, which is the slope of the line.

Your answer is: The slope of the line is -4.


There you go! I really hope this helped, if there's anything just let me know! :)
