Answer:
See below description.
Step-by-step explanation:
The function 
has the following characteristics:
- Factors:
- Zeros/roots: x=0, x=-2, amd x=1
- Positive leading coefficient
- Graph starts up, curves down through -2 on the x-axis and back up to 0 where it touches and curves down and back up again again. It comes down back through 1 and crosses.
- Its graph s the shape of a W.
- It has minimum values at -2.83 and -0.397
Answer:
m = 7/6
m = -4/9
Step-by-step explanation:
y2 - y1 / x2 - x1
The formula to find the slope.
The answer is C though.
I am sure of it from what i remember whenever i was in 9th
The mean is calculated by adding up all of the given numbers and dividing by the number of numbers.
Lets, for ease of understanding, say that the first three number were 64...
Mean=(64+64+64)/3=192/3=64
Now, lets solve for the mean where 'x' is the unknown fourth number and 128 is the mean. (since, the answer said that when the fourth number was added the mean, 64, was doubled '64*2=128')
128=(64+64+64+x)/4
128=(192+x)/4
Multiply both sides by 4
512=192+x
subtract 192 from both sides
320=x
The missing number is 320..
Now lets double check our work.
Mean=(64+64+64+320)/4=512/4=128
Answer=320
