Answer:

151

Step-by-step explanation:

Given the following scores

132,140,130,190,112,200,185, 172,163,151,149 . What isn’t the median ?

Median can be gotten whenever we arrange a set of scores in ascending or descending order.

Arranging the above scores in the ascending order, we have

112,130,132,140,149,151,163, 172,185,190 and 200

Let f(x)=(x-2)^3+8 Find the inverse of f(x). Please show steps in written form would be gladly appreciated
Tatiana [17]

Hello from MrBillDoesMath!

Answer:

(x-8)^(1/3) +2

Discussion:

To find the inverse of a function swap the values of x and y in the original equation y = (x-2)^3 +8  and solve for y.

y = (x-2)^3 +8          =>  original function. swap x and y values

x = (y-2)^3 + 8        =>  subtract 8 from both sides

x - 8  = (y -2)^3        =>  take cube root of both sides

(x-8)^(1/3) = y - 2     => add 2 to both sides

(x-8)^(1/3) +2 = y      => y is the inverse



Thank you,

MrB
