Answer 1

Answer:

Q1(A) Q(s)= 1 is not the zeros and Q(s)=-4 is also not the zeros

STEP BY STEP EXPLANATION:

Put the values firstly:

• Q(s) =-4(x)³+7(x)²-24

Q(-4)= -4(-4)³+7(-4)²+24

= -4(-64)+7(16)+24

=265+112-24

=368-24

=344 (SO Q(-4) IS NOT THE ZEROS OF THE GIVEN POLY.

•Q(s)=-4(x)³+7(x)²-24

=-4(1)³+7(1)²-24

=-4(1)+7(1)-24

=-4+7-24

=-28+7

=-21 (SO Q(1) IS ALSO NOT THE ZEROS OF THE GIVEN POLY.

Q:5(a) FALSE (BECAUSE WE CAN SEE THAT THE HIGHEST DEGREE IS 5 IN THE GIVEN POLY.)

(b) YES ITS A POLY. (BECAUSE IT DO NOT CONTAIN ANY NEG. EXPONENT)
