Answer:
-1
Step-by-step explanation:
Replace x with -2
f(-2)=-(-2)^2+3
Solve.
f(-2)=-4+3
=-1
I hope this helps!
When you have f(x) =- x^2 +3 and want to find f(-2), it is basically asking you to calculate the function where x is -2. So if you plug in -2 for x you get:
-(-2)^2 + 3= f(-2)
-4+3= f(-2)
-1=f(-2)
