As the graph approach negative infinity the graph move to positive infinity as the graph approach positive infinity the graph move to negative infinity
Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons
so this is the formula
c² - b² = x²
insert the numbers on the triangle in the picture
21² - 8² = 377
since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~
Answer: x = 19.4
It is false. Although integers above 0 divided by 0 is 0, negative numbers can also be integers (-1,-3,-10, etc.), and when they are divided by zero, they are undefined. That means that it is not really a number.
