find f(a), if f(t) = 2t2(squared)-t-2
A. 2(a+t)2(squared)-2t+1-2
B. 2(t+a)2(squared)-2(t+a)-2
C. 2a2(squared)-a-2
D. 4a2(squared)-2a-2
I put (squared) because the two in front of it means it's being squared... please help. thanks!

Yes, it's C.
Change all the t's to a's in
f(t) = 2t2(squared)-t-2
you get
f(a) = 2a2(squared)-a-2

To find f(a), we substitute the variable t in the function f(t) = 2t^2 - t - 2 with the value a.
So, we replace every occurrence of t with a in the function:
f(a) = 2(a)^2 - (a) - 2
= 2a^2 - a - 2
Therefore, the answer is C. 2a^2 - a - 2.
