Question

p(x)=x³+x²-2x+1 by g(x)=x+3

Answer 1

g(x) = x+3
so, g(-3)
p(-3)=(-3)³+(-3)²-2(-3)+1
-27+9+6+1
-12 +1
-11
Hope this helps you friend
thanks

Answer 2

g(x) = x + 3

g(x) = 0

x + 3 = 0

x = -3

Put it in p(x)

x³ + x² - 2x + 1

(-3)³ + (-3)² - 2(-3) + 1

-27 + 9 + 6 + 1

= -11


Thank you.
