Question

A point P in the first quadrant lies on the graph of the function f(x)=x^2. Express the slope of the line joining P to the origin as a function of x.

Answer 1

Point has dah coordinates as P = (x,x^2)
Dah origin has dah coordinates as O = (0,0)
now dah slope of the line from point P to origin = (x^2-0)/(x-0) = x^2/x = x
So dah slope = m = x
