Answer:
(2 + 1 ) − 4 2 + 2
Step-by-step explanation:
1. Eliminate redundant parentheses
( 2 + 1 ) − 4 2 + 2 2 + 1 − 4 2 + 2
2 . Add the numbers
2 + 1 − 4 2 + 2 2 + 3 − 4 2
3. Rearrange terms
2 y +3 − 4 2 − 4 2 + 2 + 3
-4y^2+2y+3
(2y+1)-4y^2+2
2y+1-4y^2+2
-4y^2+2y+1+2
F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
Now you have 132 + 5 = 137
F(11) = 137
