If f(x) = x − 7, find the following.
a f(13)
b f(-6)
c f(p)
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.
To find a specific value of a function, you need to substitute the given value into the function and perform the appropriate calculations.
a) To find f(13), substitute 13 into the function:
f(13) = 13 - 7 = 6
Therefore, f(13) = 6.
b) To find f(-6), substitute -6 into the function:
f(-6) = -6 - 7 = -13
Therefore, f(-6) = -13.
c) To find f(p), substitute p into the function:
f(p) = p - 7
Therefore, f(p) = p - 7.
