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!

Which answer would you choose if you replace all the "t" on the right hand side of the function definition by "a"?

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
