A polynomial expression can only be categorized into a function if and only if a single input can only have one and only output. This means that there should be no more than one dissimilar values of y for the same value of x.
Evaluating the givens above, it can be observed that there are two -1's as an x-coordinate and it has two outputs, 0 and 1. Thus, we can remove either (-1,0) or (-1,1) for the relationship to become a function.
Answer:
a
Step-by-step explanation:
g(x)=-x²
f(x)=|x+2|
f(3)=|3+2|=5
(g*f)(3)=g(f(3))=g(5)=-5²=-25
Ok first you have to figure out the amount of cans produced in a minute by the machines. So do 7200 divided by 200 and 7200 by 300 to get 36 Cans per minute on the new machine and 24 Cans per minute on the old one. So now we need to figure out an equation to figure out the amount of time needed to make 7200 cans with them working together which means addition. The equation will be 36x+24x=7200 which can be simplified to 60x=7200 and your answer for total amount of time will be in minutes. You should get 120 minutes.
By writing an equation you can easily solve this:
18+ X + 4X - 1 = 42
•we need the answer to 4X-1
1. put the parts that include the X parameter in one side and the integer numbers in one side :
X + 4X = 25
5X= 25
X= 5
2. 4X-1 —> 4x5-1 = 19
