tressed a bit about it, I am wondering if you could help me? I would be really glad and thankful!!
I am polish by the way so sorry about it, but here is the task:
2.81. Investigate whether there are values of k, m (k, me R) parameters for which the function f is differentiated in the set R. Find f '.
I attached an image also, I would be really thankful for any kind of help! Jeśli means 'If'
ave a horizontal tangent line at x = 1 ? (Without using differentiation rules)
For each statement, explain why it must be true, or use an example to show that it can be false.
a)If y = f ( x ) has a horizontal tangent line at x = 1 then y = g ( x ) , where g ( x ) = f ( x − 1 ) + 1 , has a horizontal tangent line at x = 2 .
b)A tangent line always has exactly one point in common with the graph of the function.
