Answer:
The zeros are the points where the parabola intercepts the x-axis.
where a is some constant
If the parabola passes through point (3, 4) then:
So the equation of the parabola is:
Or in standard form:
An irrational number/value is one you cannot express in terms of a ration, or a fraction, it cannot be written as fraction
now 291.87... is simple, two decimals, so you use two zeros at the botom and end up with
and boom, there you are, a fraction, nice and dandy
now, let's see the first one -√(127) well, low and behold, 127 is a prime number, and and thus is has no two factors that'd serve as root, so, there's no rational root that'd give that, that makes it irrational
