The manufacturer of an mp3 player wanted to know whether a 10% reduction in price is enough to increase the sales of its product. to investigate, the owner randomly selected eight outlets and sold the mp3 player at the reduced price. at seven randomly selected outlets, the mp3 player was sold at the regular price. reported below is the number of units sold last month at the regular and reduced prices at the randomly selected outlets.

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

)
