i only found the maximum point and then didn't know what to do next

Omg, i cant believe i got it right but one: the final answer which the question demanded be in closest RM, i thought i had to round it up. Edit: i answered 697 btw. Do you think they'll overlook this?

I believe the spm marker is quite linean in marking.They tried their best to make student get marks by showing necessary working steps.If you round off the final answer to the nearest RM,they shall give you full marks.

I think I still remember it ask the final question the answer must be in nearest integer/ringgit something so I answer 697

This question seems invalid by most of students by not stating point E as the origin of the curve in the question.But if a student are able to make an assumption point E as the origin,the rest of the points (x,y) on the right side of point E are positive,then this question shall be easy and answerable.

I think many got confused because based on my experience doing trial papers they will state which point is the origin but this time they didn't mention? I wasted 15 minutes+ on this question because of that reason. But thank goodness able to figure it out and get answer surd 8/3

good job , at least u can do
@shayneplays6609 4 ай бұрын
Bruh u don’t need the question to state the origin the information about the equation is enough
@oxbmaths Жыл бұрын
If the question does not specify that E is the origin, then it is an incomplete and unfair question! Without this information, you can't prove that EH = 3+p. The origin could be to the left or right of E. Also, b(ii) is a let down after all the analysis required for the other parts.
@mathew_pang Жыл бұрын
Yes i am agree with you! for this kind of questions, it should accept different kind of answer if axis is not given. therefore it is not a good question after all
@mohdalhanafi7567 Жыл бұрын
It can be done if you integrate the dy/dx and use the point (3,0) to complete the quadratic equation

Bro u don’t need to know where the origin is find the roots and minus
