Hi
The √9 is = 3
because 3²= 3*3=9
I hope that's help !
The required slopevalues are : 1, -2 , 2 and 0.5 respectively.
The slopeof a graph represents the rateofchangeof the graph. This gives the numerical value for how y-value changes per change in the x-value.
Decrease or decline means a negative slopeand is depicted by a minussign while increase signifies a positiveslope and indicated by a positivesign.

Answer:
Step-by-step explanation:
Given in the number of hours a group of contestants spent preparing for a quiz
The list shows as follows:
60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61
In ascending order this becomes
x 15 25 30 32 36 45 48 56 60 61 65 67 75 80 86 90
F 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2
Thus we have mode =90
All other entries have frequency 1 except 90
To find the percentage of observations between two values in a normal distribution, we can convert the values to z-scores and use a z-table to find the corresponding areas. In this case, the percentage of observations between 0.372 and 0.428 is 68.26%.
To find the percentage of observations that will lie between 0.372 and 0.428 in a normal distribution with a mean of 0.40 and standard deviation of 0.028, we need to find the area under the curve between these two values.
Using a standard normal distribution table or z-table, we can convert the values to z-scores by subtracting the mean and dividing by the standard deviation. The z-score for 0.372 is (0.372 - 0.40) / 0.028 = -1, and the z-score for 0.428 is (0.428 - 0.40) / 0.028 = 1.
By looking up the corresponding area for these z-scores in the z-table, we find that the area to the left of -1 is 0.1587 and the area to the left of 1 is 0.8413. To find the percentage between -1 and 1, we subtract the smaller area from the larger area: 0.8413 - 0.1587 = 0.6826 or 68.26%.

So far what I manage to grasp with this equation is
replacing the "x" with 3 So: f(3)= -2e^(3)
The answer ( using the scientific calculator) gave me -6
I have no Idea what are the other steps to this equation.
