Question

If p(x) = x^2 - 4x + 3, evaluate p(2) - p(-1) + p( 1/2 )

Answer 1

Answer:

-7.75

Step-by-step explanation:

p(x) = (x*x) - 4*x + 3

p(2) = 4 - 8 + 3

p(2) = -1

p(x) = (x*x) - 4*x + 3

p(-1) = 1 + 4 + 3

p(-1) = 8

p(x) = (x*x) - 4*x + 3

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

p(1/2) = 5/4

p(1/2) = 1.25

now

p(2) -p(-1) + p(1/2) = -1 - 8 + 1.25

= -7.75

Answer 2

Step-by-step explanation:

$\bf \underline{Solution-}$

We have p(x) = x² - 4x + 3

p(2) - p(-1) + p(1/2)

= (2² - 4 × 2 + 3) - {(-1)² - 4(-1) + 3} + {(½)² - 4 × ½ + 3}

= (4 - 8 + 3) - (1 + 4 + 3) + (¼ - 2 + 3)

= - 1 - 8 + ⁵/₄

= - 9 + ⁵/₄

= (-36 + 5)/4

= -31/4 Ans.
