Consider the function 
First, factor it:
The x-intercepts are at points 
1. From the attached graph you can see that
- function is positive for
- function is negative for
2. Since
the function is neither even nor odd.
3. The domain is 
the range is 
Answer:
102.5, 103.5
Step-by-step explanation:
a+a+1=206
2a+1=206
2a=205
a=102.5
103.5
I think there is a bug here. They can't be whole numbers.
Answer:
Country A = 84
Country B = 28
Country C = 18
Step-by-step explanation:
Country A, Country B, and Country C won a total of 130 medals;
A + B + C = 130 ......1
Country B won 10 more medals than Country C;
B = C + 10 .......2
Country A won 38 more medals than the total amount won by the other two;
A = B + C + 38 ........3
Substituting equation 3 to 1;
(B+C+38) + B+C = 130
2B + 2C + 38 = 130 .......4
Substituting equation 2 into 4;
2(C+10) + 2C + 38 = 130
4C + 58 = 130
4C = 130-58 = 72
C = 72/4 = 18
B = C + 10 = 18 + 10 = 28
A = B + C + 38 = 18 + 28 + 38 = 84
Country A = 84
Country B = 28
Country C = 18
Answer:
C.)
Step-by-step explanation:
There are multiple technical ways to explain this but the best one that works for me is the "vertical line test" can be used to find a function or non function. All you have to do is position your pencil vertically, place it to the far left of the graph drag it horizontally across to the right side of the graph. If your pencil is making contact with two lines at one time, it is NOT a function. Hopefully this makes sense.
