Triangle abc is translated according to the rule (x, y) - (x + 2, y-8). if the coordinates of the pre-image of point b are
(4,-5), what are the coordinates of b'?
(2,3)
(1,-9)
(-3,-4)
(6.-13)

6,-13

Step-by-step explanation:

(4.-5)

4-2=6

-5-8=-13

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

)

14

step-by-step explanation:

14 x 3 = 42
