On a two-dimensional coordinate plane, the line d = x^2 - x^3 touches the x-axis in how many places?
Choices
A) 0 B) 1 C) 2 D) 3 E) 4
Apparently it's d = x^2 - x^3 instead of d = x^2 - d^3.   In this case: the x-intercept is the value(s) of x for d = 0.   0 = x^2 - x^3;   0 = x^2(1 - x);   x = 0 or x = 1.   Answer: 2.
