The curve C 1 has equation y=a/x, where a is a positive constant. The curve C 2
Question:
The curve C1 has equation y = −a/x, where a is a positive constant.
The curve C2 has equation y = (x − b)2, where b is a positive constant.
a. Sketch C1 and C2 on the same set of axes. Label any points where either curve meets the coordinate axes, giving your coordinates in terms of a and b.
b. Using your sketch, state the number of real solutions to the equation x(x − 5)2 = 7.
