Answer:
Step-by-step explanation:
A relation is a function if there are no shared x values. If you look at the y-axis where x = 0, you can see that there are 2 coordinates that share that x value:
(0, -1) and (0, 3). Because the x value in both those coordinates is the exact same number, this is NOT a function, merely a relation. ALL functions are relations, but not all relations are functions.
The domain asks for all the included x values. It goes from the lowest x value to the highest x value. Our lowest x value is -4 and the function stops at an x value of 4. So the domain is
D = {x | -4 ≤ x ≤ 4}
The range goes from the lowest y value to the highest y value. Our lowest y value is -2 and the highest y value is 4. So the range is
R = { y | -2 ≤ y ≤ 4}
That straight line that comes after the first x and y is the line that translates to "such that". In words, our domain reads "x such that x is greater than or equal to -4 and less than or equal to 4" and the range reads "y such that y is greater than or equal to -2 and less than or equal to 4".
Answer:
x=80
Step-by-step explanation:
Take the derivative of C(x) using the power rule
C'(x)=4x-320
Set this equal to 0 and solve for x
4x=320
x=80.
Sign analysis shows this to be a minimum because for values larger than 80 C'(x)>0 and for values less than 80 C'(x)<0
Answer:
=7.071068
Step-by-step explanation
subtract the x values and y values and square them then add them together and find it's square root
