If P (x) = x3 - 4x + 3, evaluate P (2) - P (-1) + P (1 / 2)

-15/8

Step-by-step explanation:

Given P (x), we can plug in the values to find the answer.

Firstly, we need to find P (2). Plug in 2 for all the x values.

P (2) = (2) ^3 - 4 (2) + 3

= 8 - 8 + 3

= 3

Then, we can find P (-1) by plugging in all the x values with - 1.

P (-1) = (-1) ^3 - 4 (-1) + 3

= - 1 + 4 + 3

= 6

Further, we can find P (1/2) with the same process above.

P (-1/2) = (1/2) ^3 - 4 (1/2) + 3

= 1/8 - 2 + 3

= 9/8

Finally, we can evaluate P (2) - P (-1) + P (1/2) using the values solved for above.

3 - 6 + 9/8 = - 15/8
