Solutions

Chapter 1.1, Problem 49E
To determine

To find: An expression for the function whose graph is the bottom half of the parabola x+(y1)2=0.

Expert Solution

Answer to Problem 49E

The function that represents the bottom half of the parabola x+(y1)2=0 is f(x)=1x where x0.

Explanation of Solution

Solve the equation of the parabola x+(y1)2=0 and obtain the roots as follows.

x+(y1)2=0(y1)2=xy1=±xy=1±x

Since the graph is the bottom half of the parabola, consider the root with a negative radical.

Therefore, the function that represents the bottom half the parabola is y=1x where x0.
