ya its log x/base
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Yup but its fine if you don't mention in the function...fr substition u hv to use log...to find the inverse of that function you have to use one of the laws of logs
This is corrrectlog x/ base
if thats the case, then i wonder why we are asked to answer questions that involve logs in functionsLog isnt mentioned in syllabus....
Ohh you used a ruler to find that?1 cm on y axis is 5 squares
Bcozzzzzz thts the frequency i mean the actual number of students.Ohh you used a ruler to find that?
Another question, why did you take 18?
Thank youu!Bcozzzzzz thts the frequency i mean the actual number of students.
No i did not use a ruler...see a normal graph ppr tht u buy frm a shop.it has a big square in which there r 4 small squares...i considered these small squares...hope u can understand...
Thank you!1 cm on y axis is 5 squares
see for frequency 18 the frequency density is 36Ohh you used a ruler to find that?
Another question, why did you take 18?
see for the first question substitute x=4,p = 1, q = −2, r = −3 in equation y = px2 + qx + rCan someone pleaseeeee explain how to do question 7 of nov 2004, its on page 6 http://www.xtremepapers.com/papers/CIE/Cambridge IGCSE/Mathematics (0580)/0580_w04_qp_4.pdf
Thank youuu ! Can u also explain c(ii)see for the first question substitute x=4,p = 1, q = −2, r = −3 in equation y = px2 + qx + r
for second question substitute p,q, and r as shown above with y=0
For K take the formulae as y = p(-x)2 + q(-x) + r
For L take the normal formulae (y = px + qx + r) substituting y=0
That's correctok one last doubt..
matrix operator for stretch with x-axis invariant is..
k 0
0 1?
please reply asap
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
