Question

if px is equal to x^3 +2x +3 then evaluate p (2)- p(-1) + p (1/2) is equal to​

Answer 1

Answer:

Step-by-step explanation:

p(2) = (2)^x3 + 2x2 + 3

= 4x3 + 4 + 3

= 12+7

= 19

p(-1) = ( -1)^ x 3 + 2 (-1) + 3

= 1 x 3 - 2 + 3

= 3 + 1

= 4

p(1/2) = (1/2)^ x 3 + 2 x 1/2 +3

= 1/4 x 3 + 2/2 + 3

= 3/4 + 1 +3

= 3/4 + 4/4 + 12/4       by takng lcm

= 19/4
