A store puchased a Dvd for $15.00 and sold it to a customer for 50% more than the purchase price. The cuatomer was then charged a 7% tax when the DVD was sold. What was the customers total cost for the DVD? Round your answer to the nearest cent. A. $23.57
B. $24.08
C. $7.50
D. $23.55

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

i think the answer is b.

not 100% sure though.
