Question

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

Answer 1

Step-by-step explanation:

$\huge \boxed{ \fcolorbox{green}{purple}{good morning}}$

here's your answer

p(2)= (2)²-4(2)+3

=> 4-8+3

=> -1

p(-1) = (-1)²-4(-1)+3

=> 1+4+3

=> 8

p(1/2) = (1/2)²-4(1/2)+3

=> 1/4-2+3

=> 1/4-8/4+12/4

=> 5/4

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

=>-1+8+5/4

=>-4/4+32/4+5/4

=> 33/4

33/4 is your answer

Answer 2

Answer:

The value is 25/4.

Step-by-step explanation:

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

Calculating x = 2

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

      = 4 - 8 + 3

p(2) = -1

Calculating x = -1

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

       = 1 + 4 +3

       = 8

Calculating x = 1/2

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

         = 1/4 - 2 + 3

         = -3/4

Now,

Finding the value of p(2)+p(-1)+p(1/2)

by substituting the values.

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

                          = 25/4
