Evaluate abs(2 x - 7) - 3 where x = 2:abs(2 x - 7) - 3 = abs(2 2 - 7) - 3
2×2 = 4:abs(4 - 7) - 3
4 - 7 = -3:abs(-3) - 3
Since -3<=0, then abs(-3) = 3:3 - 3
3 - 3 = 0:Answer: 0
f(x)=[2x-7] -3
f(2)=[2(2)-7]-3
f(2)=[4-7]-3
f(2)=[-3]-3
f(2)= 3 -3  Remember absolute value is the distance from zero. No number will ever have a negative absolute value! :)
f(2)= 0
