If f'(x) = absolute value of (x-2) , what would teh graph of y=f(x) look like?
|dw:1335321119699:dw|
this is the graph of the derivative. looks like \(f'(x)=2-x\) for \(x<2\) and \(f'(x)=x-2\) for \(x>2\) so your original function would look something like \(f(x)=2x-\frac{x^2}{2}\) for \(x<2\) and \(f(x)=\frac{x^2}{2}-2x\) for \(x>2\)
Did u get f(x) by integrating? if so how do u integrate absolute values
in other words a parabola that faces down, and then a parabola that faces up we don't know from the derivative where the function actually is, just what the shape is. so it might look like this |dw:1335321427276:dw|
get rid of the abosolute values signs and break in to two parts
but i repeat, we don't know where the function is, just what the curve looks like
first it is a parabola that opens down, then it is a parabola that opens up
oh ok i see hpw teh graph works. but say in teh fuure ow wud i integrate a absolute value? is taht possible
