Answer should be B. What is OA?
here we have three distinct regions:
2) -3 < x < 4
3) x> 4
For 1), x+3 is -ve and 4-x is positive, so the eq becomes,
y = -3-x+4-x = 1-2x >> no solution
For 2), x+3 is +ve and 4-x is positive,
y = x+3+4-x = 7 >> this range is true.
For 3), x+3 is +ve and 4-x is positive,
y = 7.
Hence, y = 7 for all x>-3.
If x and y are integers and y = |x+3|+|4-x| , does y equal 7 ?
1) x < 4
2) x > -3
Also , please explain a little how to solve these types of questions
I am not able to do well in absolute value questions :/
