Harper, Elie, and Raina are having a skateboard race. Harper began at the starting line and rode at a constant rate of 3 feet per second. Elie got a five-foot head start and rode two feet
every 3 seconds. Raina rode 3 feet every five seconds and had a two-foot head start.

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

)

based on context clues you gave i'm assuming the answer would be c.

can you make your screen more see able?

then i might be able to .
