I have a question- The range of y = 1/(x-5) is All real Numbers True or False I think it is false because it should be all real numbers except y shouldn't equal 0. Is that correct or don't I understand it-Please explain if I'm wrong. Thanks

**Physics-Please check**

A 3.00 kg toy falls froma height of 1.00m. What will the kinetic energy of the toy be just before it hits the ground. No air resistance and g=9.81m/s Amswers: 0.98J 9.8 J 29.4 J 294 J I used the formula 1/2 m times v^2 3. times 9.8^2/2 =144. Please help-what am I doing wrong?
