Find each specified function value:

What am I doing wrong because the correct answer for (a) is 3 and (b) is

-t^3/4-5t^2/4-t+3

Here's the problem: P(x)=2x^3-5x^2+2x+3

(a) P(0) 2(0)^3-5(0)^2+2(0)^3

2-5+3 my answer I get O

(b) Here's the problem P(x)=2x^3-5x^2+2+3

P (-1/2 t)

2(-1/2t)^3-5(-1/2)^2+2(-1/2)+3

2(-1/8)-5(1/4)-1+3 my answer 1/2
