Question

7. If p(x) = x 4x + 3, evaluate: p(2)-P(-1)+p​

Answer 1

Step-by-step explanation:

p(x)=x²-4x+3

so,

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+1 =5/4

now,

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

=(-1)+8-5/4

=7-5/4

=28-5/4

=23/4

Answer 2

question...........

p(x)=x

4x+3

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

p(2)=4×2+3

=11

p(-1)=4×-1+3

=-1

p=4+3

=7

your question

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

11+1+7
