When Karen was born, the dad is 22 so Karen is now 27 which means the dad is 22+27= 49
The domain is the value of x. In this case, -3≤x≤7
the range is the value of y. in this case, -1≤y≤9
this is not a function, because the same x value has two corresponding y values. For example, when x=5, y=0 or y=8
It IS a function if every x value has only one corresponding y value.
Answer:
6
Step-by-step explanation:
y + 1
= 7
y + 
= 
y = 40/6 = 20/3 = 6
First: 0
Second: 0
Third: -5
Fourth: y=4x
