Answer:
The range is:
{-4, 1, 2, 5, 8}
Step-by-step explanation:
Given the function

- We know that the domain of a function is the set of input or argument values for which the function is real and defined.
As the domain interval -2 ≤ x ≤ 2
i.e. the values in the domain = {-2, -1, 0, 1, 2}
- We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
As the domain interval -2 ≤ x ≤ 2
Putting all the x-values in the domain interval in the function
so
putting x=-2 in the function


putting x=-1 in the function


putting x=0 in the function


putting x=1 in the function


putting x=2 in the function


Thus, when we put the domain values, the corresponding range values are:
x y
-2 -4
-1 1
0 2
1 5
2 8
Therefore, the range is:
{-4, 1, 2, 5, 8}
Random sampling is defined as a method of selecting a sample from any population in such a way that every selected sample had a predetermined probability of being selected.
So,the true statements for this scenario are :
The owner chooses 20 of the slips of paper without looking.
The owner sends a survey to all clients whose phone number ends in 5.
Answer:384cm²
Step-by-step explanation:
first find the area of the parallelogram
bh
b=24
h=7.5
24×7.5=180
second find the area of a rectangle
lw
l=24
w=8.5
24×8.5=204
add the areas together
204+180=384cm²
Answer:
max{x²-4x²+5} = 5 at x = 0
Step-by-step explanation:
1. Find the critical numbers by finding the first derivative of f(x), set it to 0 and solve for x.

We get:

So the critical number is x = 0.
2. Evaluate the first derivative by plugging in the critical number and see if the derivative is positive or negative on both sides:
is positive when the x < 0 (for example: -6*(-1)=+)
is negative when the x > 0 (for example: -6*(1)=-)
Therefore, you have a local maximum.
Now just get the Y value by plugging in the critical number in the original function. 
local maximum is (0,5)
