Question

Evaluate f(x) = –x2 + 1 for x = –3. –9 4 –4 –8

Answer 1

Answer:

D -8

Step-by-step explanation:

Answer 2

Answer:

-63

Step-by-step explanation:

Write the problem as a mathematical expression.

$f(x)=-x^2+1$  $for$ $x =3-9$ $4-4-8$

Simplify  4−4−8  to substitute in f(x)=−x^2+1

Subtract  4  from 4

$0-8$

Subtract  8  from 0

$-8$

Replace the variable  x  with  −

8  in the expression

$f(-8)=-(-8)^2+1$

Simplify

$f(-8)=-64+1$

$f(-8)=-63$

Answer = -63
