When x is 0 for the equation y=10/x, y is obviously 0. How can i explain why this happens in words? and i know that division is finding how many times one number is contained in another. Is it 10 goes into 0, 0 times or 0 goes into 10, 10 times?

Answer 1

When x is 0 for the equation y = 10/x, y is NOT 0.
It is infinity.

0 goes into 10 an infinite number of itmes. Nothing gets taken away.

Answer 2

oh infinity?

or is it undefined?

Answer 3

Same thing. Math teachers like to say "undefined".

Graph the function and you will see what happens when x approaches zero. It (10/x) goes "off the page" and approaches infinity

Answer 4

oh i see!
thank you very much
