Answer 1

Answer:

p(2)-p(-1)+p(1/2)=-35/4

Step-by-step explanation:

p(x) = x^2-4x+3

p(2) = (2) ^2-4(2) +3= 4- 8+ 3 = - 1

p(-1)=(-1) ^2-4(-1) +3 = 1 + 4 +4 = 9

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

p(2)-p(-1)+p(1/2)= -1 -9+ 1 1/4

= -10+1+1/4

= -8 3/4

= -35/4

p(2)-p(-1)+p(1/2)=-35/4
