Write a function to represent the set of ordered pairs. {(2, -2), (3, 8), (4, 22), (5, 40)} A) f(x) = -x B) f(x) = x - 4 C) f(x) = x2 - 6 D) f(x) = 2x2 - 10

The correct answer is option D. f(x) = 2x2 - 10

Step-by-step explanation:

The ordered pairs are: (2, -2), (3, 8), (4, 22), (5, 40)

And the function is f(x) = 2x2 - 10.

for the ordered pair: (2, -2)

                     f(x) = 2× - 10 = -2 (satisfied)

for the ordered pair: (3, 8)

                     f(x) = 2 × - 10 = 8 (satisfied)

for the ordered pair: (4, 22)

                     f(x) = 2× - 10 = 22 (satisfied)

for the ordered pair: (5, 40)

                     f(x) = 2 × -10 = 40 (satisfied)    

Thus we can conclude option D as correct answer  

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
