Answer:
y = (-5/2)x + 1
Step-by-step explanation:
y = (-5/2)x + c
When x = 2, y = -4
-4 = (-5/2)(2) + c
-4 = -5 + c
c = -4 + 5 = 1
1) domain of the first is ( R ) because of its root(3) and its range is (R) because of its root again
2)and domain of the last , is [0,+infinity)
and for its range , you can draw it such as picture and will be [0,- infinity)
