On a two dimensional coordinate plane, the curve y=x^2 - x^3 intersects the x-axis at how many points?
A. 0
B. 1
C. 2
D. 3
E. 4
I got the answer as B,
The way i solved the question was to find at how many points a curve touches x axis is by putting y = 0 , when we put y=0 then we get the equation x^2 - x^3 =0
So x^2 = x^3, so cancelling x on both the sides we get x = 1
so the curve touches x axis at x=1 so the answer is B,
But the official answer is C, wat is wrong my method of solving ?
