Question

find p(1),p(2),p(3),p(0)if p(x)=2xsquare -3x+1​

Answer 1

Answer:

let p(x)=2^2-3x+1

replace x=1

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

=4-3+1

1+1

p(1)=2

let replace x=2

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

=4-6+1

=5-6

p(2)=-1

let replace x=3

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

=4-9+1

5-9

p(3)=-4

let p(x)=0

2^2-3(4)+1

4-12+1

5-12

p(3)=-7
