Question

se p(x) = x² - 4x + 3
Find p (2) - P(-1) + p (½)​

Answer 1

Answer: -19/4

Step-by-step explanation:

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

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

p(-1) = (-1)^2 - 4*(-1) + 3 = 5

p(1/2) = (1/2)*2 - 4*(1/2) + 3 = 1/4 + 1 =  5/4

p(2) - p(-1) +p(1/2) = -1 -5 + 5/4 = 5/4 - 6 = 5/4 - 24/4 = (-19/4)
