Question

Draw the graph of polynomials
$p(x) = x^ - 7x + 12$
​

Answer 1

p(1)=1^-7(1)+12

= 1-7+12

= -6+12

= +6

( 1,6)

p(2) =2^-7(2)+12

=4-14+12

=-10+12

=+2

(2,2)

p(3)= 3^-7(3)+12

=9-21+12

=-21+21

=0

(3,0)

p(4)= 4^-7(4)+12

=16-28+12

=-28+28

=0

(4,0)

p(5)=5^-7(5)+12

=25-35+12

=-10+12

=+2
