Answer 2

It seems like you want to evaluate the expression as x approaches 1/2:

lim(x -> 1/2) (2x^3 - 5x^2 + x - 4).

To find the limit, substitute the value of x into the expression:

lim(x -> 1/2) (2*(1/2)^3 - 5*(1/2)^2 + 1/2 - 4)

Simplify the expression:

= lim(x -> 1/2) (1/4 - 5/4 + 1/2 - 4) = lim(x -> 1/2) (-9/4 - 3/4) = lim(x -> 1/2) (-12/4) = lim(x -> 1/2) (-3).

Therefore, the limit as x approaches 1/2 of the given expression is -3.
