Answer:
A function can be any set of points where one input is equal to one output. You cannot have two X values with the same Y value, for example.
<u>I believe the answer is neither</u> because in both sets you can see they have different Y values for the X values 2 and 9.
Answer:
x = -2 or 5
Step-by-step explanation:
y = (x-3)/((x-5)(x+2))
y is undefined when the denominator is zero.
The answer would be:
y = 5
x = 4
Use gradient formula, rise over run.
y2-y1/x2-x1
Answer:
I came up with -12
Step-by-step explanation:
8 workers = 6 days to complete
x workers = 4 days faster to complete
6/4=1.5 days faster
1.5 x 8 = 12 workers needed to complete the wall in fours days
