How to do this question :
A) find the equation of the tangent to y= square root of x, -1. Where x=t
I differentiated this , then sub in t for x .

To write square roots like that without LaTeX, it is probably good to write it like this: y = sqrt(x) - 1.The correct question was leehuans interpretation
Can somebody show how to solve the inequality g(x)>0, where g(x)= 1/x+3 - 2
how did you get : 0< x+3< 1/2
Also how would you determine the range and domain for this? What steps are taken
Q. A function is defined by f(x)=ax^2+bx+c. It is known f(x) is odd, and f(5)=25. Fin a,b and c
I got b = -5 , but I don't know how to find a and c ?
How would you apply the formula : f(-x)=-f(x) to get a and c
What he's saying is that if you think about it, if you have a quadratic x^2 lying around, it can't be an odd function; has to be even.How would you apply the formula : f(-x)=-f(x) to get a and c
The locus can only be a full circle if the altitudes are allowed to project from the triangle extended outside the circle when the triangle is obtuse. If this is not the case, then you only get a circular arc.
