Answer 1

Answer:

mark me as a brainlist !!!!

^_~

Step-by-step explanation:

at x=3:-

3(3)^3-4(3)^2+7(3)-5=3*27-4*9+21-5=61

----------------------

when x= -3

3*(-3)^3-4*(-3)^2+7*(-3)-5=  3*(-27)-4*9+7*(-3)=-143

Answer 2

solution:x=3

p(x) = 3×3-4×3×2+7×3-5

=9-12×2+21-5

=-3×2+16

=-6+16

therefore ,p(x) =10
