Respuesta :
[tex]f(x)=-x^2+1[/tex]
Plug in the value [tex]x=-3[/tex] into this function
[tex]f(-3)=-(-3)^2+1[/tex]
[tex]=-(9)+1[/tex]
[tex]=-8[/tex]
Thus, your answer will be D) -8. Let me know if you need any clarifications, thanks!
Answer:
D. -8
Step-by-step explanation:
We are given
f(x)= -x^2+1
and asked to evaluate f(x) for x= -3. Therefore, we must substitute -3 for x in the function.
f(x)= -x^2+1 for x= -3
f(-3)= -(-3^2)+1
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, evaluate the exponent: -3^2
-3^2= -3*-3= 9
f(-3)= -(9)+1
f(-3)=-9+1
Next, add -9 and 1
f(-3)= -8
When f(x)= -x^2+1 is evaluated for x= -3, the result is -8. Therefore, the correct answer is D. -8
