What you have done is correct. To make sure, what is the rate of change of ? Its the slope! 5!!!!!!!
Please help me with this. I get stuck at the part:
(5(x + h) - 4) - (5(x) - 4)/x + h - x
What do I do after that? Do I continue with this?
(5(x + h) - 4) - 5(x) + 4/h
5x + 5h - 4 - 5(x) + 4/h
Please help me I am utterly confused on how to solve this problem. Thank you so much in advanced
