what my lecture explain when study before is just about what the definition about f’(x), in his explanation :
f’(x) = lim h->0 [(f(x+h) - f(x)]/h
and then :
f’(x) = 1/(2*sqrt[x])
no explanation in my lecture about somethink like read the graph in my op, also the graph type isn’t familiar for me...
sorry for typo, yes it should be “rate of change”, my bad when i’m translated the question in my language to english
i’m still confused how to answer 3 of question, is there the link for explanation something like my op
(sorry if my english are bad)
1. How to get f’(1), f’(2), f’(3), and f’(5)
2. How to calculate average speed change of y to changes in x in the interval [0,6]
3. Estimate value of f’+(0) and f’-(6)
pls help me about this graph, i dont know how to read this 🙏
