If f(x) = x − 7, find the following.

a f(13)
b f(-6)
c f(p)

4 answers

f ( x) = x − 7

Just replace x with the given values​​.

f ( 13 ) = 13 - 7 = 6

f ( 6 ) = 6 - 7 = 1

f ( p ) = 9 - 7
Correction:

f ( - 6 ) = - 6 - 7 = - 13
a ) f ( 13 ) = 13 - 7 = 6

a ) f ( - 6 ) = - 6 - 7 = - 13

c ) f ( p ) = p - 7
Thank you very much I see how this all works out. Thank you for the guide.

Have a wonderful day, and just wanted to say I appreciate everyone there that gives there time to help someone like me that just sometimes can not get it together.
