Answer:
A. a parabola that opens down.
Step-by-step explanation:
First we can eliminate two answers, b and d, since parabalas that open left or right use the y variable.
Now the equation of a standard parabola is x². This means that there are no negative y values, and therefore it cannot open down, it is up.
With a NEGATIVE coefficient, the graph is flipped over the x axis, therefore making it open down.
Graphical proof is attached for further understanding, positive a is in red, negative a is in blue.
4.43
To find the mean (average) # of sick days taken, you add all the numbers, then divide by the number of employees.
31 ÷ 7 = 4.4285714286 or aprox. 4.43
Take two points that you found , any 2 points. for example (-2,-4) and (1,-1)
draw them on the graph and than draw a straight line that cross both.
this is the line of your equation
The answers are
3/8, 2/5, 11/25, 5,10
