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
