Here is the data set for the graph (The colors are just to help you keep track):
2.5, 2.5,3,3,3.5, 3.5, 3.5, 3.5, 4, 4, 4.5, 4.5, 4.5.4.5,5,5,5,5,5,5,5,5,5.5, 6.
6. 6.5, 6.5
1. Find the mean of the data.
2. Find the median of the data.
3. What do you notice about the mean and median?

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

x = 3 ± √(5+y)
