Question

hlo dear pls solve this question hurry.​

Answer 1

Step-by-step explanation:

con 1)

p(x=2)=x²-4x+3

p(x=2)=2²-4(2)+3

p(x=2)=4-8+3

p(x=2)=7...........(1)

con, 2)

p(x=-1)=x²-4x+3

p(x=-1)=(-1²)-4(-1)+3

p(x=-1)=-1+4+3

p(x=-1)= -2.....(2)

con 3)

p(x=1/2)=(1/2)²-4(1/2)+3

p(x=1/2)=1/4-4×1/2+3

p(x=1/2)=5/4......(3)

ACCORDING TO QUESTION..

P(2)-P(-1)+P(1/2)

7-(-2)+5/4

7+2+5/4

9+5/4

=41/4
