State whether each of the following functions f have a well-defined inverse or not. Recall that a function has an inverse if, fo

r every element in the codomain, there exists exactly one element in the domain that maps to it; that is, the function is onto (surjective) and one-to-one (injective). If it does, provide the inverse function f −1 . If it does not, explain if it violates the onto condition, one-on-one condition, or both, and justify your response. (a) f : R → R, f(x) = 3x−12 (b) f : R → R, f(x) = x 2 +1 (c) f : R → R, f(x) = 3x 3 −12x (d) f : R + → R +, f(x) = √ x+1, where R + denotes the positive reals

8. Mitchell bought 600 shares of Centerco two years ago $34.50 per share. He sold them yesterday for $38.64 per share.
g100num [7]

Answer:

a. percentage increase in price per share = 12%

b. The total purchase price for the 600 shares is $20,700

c.  The profit for the 600 shares is $2,484

d.  The profit for the 600 shares is $2,484

Step-by-step explanation:

a. Initial price per share    =  $34.50

Current price per share = $38.64

Change or increase in price =  $38.64 - $34.50 = $4.14

percentage increase in price per share = 12/34.50 x 100% = 12%

b. Total number of shares     =  600

    Price                                   =   $34.50

   The total purchase price for the 600 shares = ($34.5x600) = $20,700

c.  Total cost of 600 shares   =  ($34.5x600) = $20,700

     Total revenue from sales =  ($38.64x600) = $23,184

     Profit from the 600 shares = Total selling price - total cost price

                                                  = $23,184 - $20,700 = $2,484

d.  Total cost of 600 shares   =  ($34.5x600) = $20,700

     Total revenue from sales =  ($38.64x600) = $23,184

     Profit from the 600 shares = Total selling price - total cost price

                                                  = $23,184 - $20,700 = $2,484

Next number in sequence 3 -6 12 4 20 ?
Artyom0805 [142]
-6 - 3 = -9
12 - (-6) = 18
4 - 12 = -8
20 - 4 = 16
The first difference is -9. The third difference is -8.
Maybe the fifth difference is -7.
That makes the next term 13.
