Question

if p(x)=x-4x+3 evaluate p(2)-p(-1)+p(1/2)

Answer 1

p(2)=(2)-(4)(2)+3
=2-11= -9
p(-1)=(-1)-(4)(-1)+3
= -1+7= 6
p(1\2)=(1\2)-(4)(1\2)+3
=(1\2)-2+3=(1\2)+1
=(3\2)
p(2)-p(1)+p(1\2)
=(-9)-(6)+(3\2)
=-15+(3\2)=(33\2)

Answer 2

Hi Friend !!!

Here is ur answer !!!

p(x) = x²- 4x + 3

p(2) = 2²- 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+12/4

= 7/4

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

= -1 - 8 +7/4

= -4-32+7/4

= -29/4


Hope it helps u : )
