Ответ:
1. a) Not function
b) Domain is all real numbers greater than or equal 2 (x ≥ 2)
c) The range all real numbers ( -∞ < y < ∞)
2. a) Function
b) The domain is all real numbers (-∞ < x < ∞)
c) The range is all real number greater than or equal -4 (y ≥ -4)
3. a) Not function
b) domain is {-3 , -2 , -1 , 0 , 1 , 3}
c) The range is {-2 , -1 , 1 , 2 , 3 , 5}
Step-by-step explanation:
1. Not a function because some x has more than one corresponding y
Note: If we draw vertical line and move it left and right over the curve it will cut the cure in more than one point that means one x has more than one y
2. Function because every x has one corresponding y
3. Not function because some x have more than one corresponding y like
(-3 , -2) (-3 , 2) and (3 , -1) (3 , 2)
