A True
The first condition gives that the function is in fact a function and the second condition makes it a one to one
Sum is for addition and the numbers can only be 1 number apart so the answer is
4 and 3
I believe this is correct if not please let me know.
1 gallon=3.78541 liters
So 1 gallon is bigger than 2 liters
I'm assuming the function is f(x) = 100(0.7)^x. This is the same as y = 100(0.7)^x because y = f(x).
Plug in x = 0 to get
y = 100(0.7)^x
y = 100(0.7)^0
y = 100(1)
y = 100
So (x,y) = (0,100) is one point on this function curve
Plug in x = 2 to get
y = 100(0.7)^x
y = 100(0.7)^2
y = 100(0.49)
y = 49
So (x,y) = (2,49) is another point on this curve
In summary, the two points on this function curve are (0,100) and (2,49)
