Question

Find the value of f(x) = x 2 +2x+1 when x = -1.​

Answer 1

Answer:

5

Step-by-step explanation:

-1(2) + 2(-1) + 1

-2 + (-2) + 1

4 + 1

= 5

Answer 2

Answer:

0

Step-by-step explanation:

$f(x)=x^2+2x+1$

Substituting -1 in place of x

$f(-1)=(-1)^2+2(-1)+1$

$f(-1)=1-2+1\\f(-1)=-1+1\\f(-1)=0$
