First:   f(2) is same as  f(x=2) so all we have to do is to express x=2 in f(x)
f(2) = 3*2 + 2 = 8

Second
 f^(-1) (3) is inverse function.  first we solve f(x) for x.
let f(x) be equal to some variable m
m = (2x -7)/3
3m = 2x - 7
2x = 3m + 7
x = (3m + 7)/3
now we write:
f^-1(x) = (3x + 7)/3

x=3
f^-1(3) = 16/3

Third
  2y + 14 = 4y - 2
      we just solve for y
     2y = 16
      y = 8

Now we take that f(x) = y because we both write to be the functions of x

that means that First and third have same result.

X2 - 7x + 9 =0 please leave answer in surf form and simplify ​
777dan777 [17]

Answer:

x = \frac{7}{2} ± \frac{\sqrt{13} }{2}

Step-by-step explanation:

Given

x² - 7x + 9 = 0 ( subtract 9 from both sides )

x² - 7x = - 9

Solve using the method of completing the square

add ( half the coefficient of the x- term)² to both sides

x² + 2( - \frac{7}{2} )x + \frac{49}{4} = - 9 +

(x - \frac{7}{2} )² = \frac{13}{4} ( take the square root of both sides )

x - \frac{7}{2} = ± \sqrt{\frac{13}{4} } = ± \frac{\sqrt{13} }{2} ( add

x = \frac{7}{2} ± \frac{\sqrt{13} }{2} = \frac{7+/-\sqrt{13} }{2}

Considering the dot plot, we have that only 7 of the 25 measures are ratings of at most 6, that is, 6 is less than both the mean and the median of the distribution, hence it is not a good description of the center of this data set.

<h3>What is a dot plot?</h3>

A dot plot is a graph shows the number of times each measure appears in the data-set.

From the plot given in this exercise, it is found that only 7 of the 25 measures are ratings of at most 6, that is, 6 is less than both the mean and the median of the distribution, hence it is not a good description of the center of this data set.
