a class has 32 pupils 18 are boys the others are girls 12 pupil from this class went on trip one of these 12 pupils is chosen at random there is an even chance that the chosen pupil is a girl how many girls stayed in the class

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

)
