f(x) = -x² + 3
f(-2) = -(-2)² + 3 = -4 + 3 = -1
Answer → f(-2) = -1
To figure out you would first find a common factor with would be 12. After that 1/4 would be 3/12, 1/3 would be 4/12 and 1/6 would be 2/12. Next you just add all the numbers and get 9/12 then the remainder is you answer which comes to be 3/12 or 1/4. Hope that helps:)
