David N. Goliath is planning to open a sporting goods store. However, the initial investment is $120,000. He currently has this money in a certificate of deposit earning 10 percent. He may leave it there if he decides not to open the store. If he opens the store and it is successful he will generate a profit of $50,000. If it is not successful, he will lose $90,000. What would the probability of a successful store have to be for David to prefer this to investing in a CD?

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

)

x=0
