-9 is x
mark me brainliest if the answer is correct, thank you in advance :)
It is going to be A hope this helps
You replace x with (a+1)
Then f(a+1) = (a+1)^2+1
= a^2+2a+1+1
= a^2+2a+2
Multiply and when you get ur answer, add it to 533
Simply take the derivative of s(t),
s'(t) = -6
Since the velocity is constant, v(t) = s'(t) = -6 at any given time t.
