The graph of a quadratic function is represented by the table.

x f(x)

6 -2

7 4

8 6

9 4

10 -2

What is the equation of the function in vertex form?

Substitute numerical values for a, h, and k.

$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
