Once you have your euation of form y = m x + b or y = A sin x or y = a x^2 + b x + c or whatever you think kind of fits the pattern, Then you put in any old x you are interested in and get y
I am not sure what this is about. My guess would be what I call curve fitting the data. In the simple case you try to find the best straight line that goes more or less through the data points. If you do this by minimizing the sum of the squares of the differences between your...
(4, 0), (3, −1), (6, 3), (2, −4) Which are solutions to y = x − 4 (4, 0) 0 = 4 - 4 true (3, −1) -1 = 3-4 true (6, 3) 3 = 6 - 4 false (2, −4) -4 = 2 -4 false
I do not know what you did with Steve
a closed equation is a statement of fact that may be true or false eg 2 + 2 = 4 closed true 3 + 2 = 5 closed false an open equation is one where it may or may not be true depending on the value of a variable eg x + 2 = 4
sorry typo, 13 not 8
(-oo,3] U [13,+oo)
(-oo,3] U [8,+oo)
well x can not be in the part of our number line from 3 to 13 but 3 and 13 are ok 3 >/= x >/=13
lethargic ? sluggish ?
for all we know the acceleration is constant. I actually suspect the force is greatest when pushing off the starting block and therefore acceleration is greatest at the start (F = m a), but there is nothing in your statement to help us with a versus t. Therefore assume a is co...
