A postcard has an area of 10 square inches. Two enlargements of the postcard have areas of 40 square inches and 160 square inches. In each postcard, the length is 2 1/2 times the width.

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

)

here the number -5 is all of the following except a rational number.
