Answer 1

Answer:

$\huge\mathcal{\purple{answer}}$

...............

The given g(x)= -1

The given P(x)=x³+2x²-5x+7

P(-1)= (-1)³+2(-1)²-5(-1)+7

= -1-2+5+7

P(-1)= 9

The value of p(-1) is 9

Answer 2

Answer:

13

Step-by-step explanation:

p(x)=x×3+2×2-5×x+7

= -1×3+2×2 -5× -1+7

= -3+4+5+7

= 13
