Calculus Grade 12: Where is the graph increasing?

[Asra_Fareed]

Hi Kevin.💫 I dont agree with the solution above. Because the question asked, for which values of x is f'(x) >0.

This means for which values of x is the graph f'(x) lying above 0 (the x-axis). And to solve that we will need to find the two x intercepts of the parabola.

And our solution will be something like 2<x<5.

If the two x intercepts are for e.g. 2 and 5.

That is whats supposed to happen. In my opinion. Let me know what you think.😊👍
