You must use Pythagorean theorem, which is
a and b are both legs (the two legs are the sides that form a perpendicular right angle) while c is the hypotenuse (side opposite the right angle)
In this case...
a = y
b = 8
c = 12
^^^Plug these numbers into Pythagorean theorem
Simplify as much as possible
+ 64 = 144
Isolate y by subtracting 64 to both sides
+ (64 - 64) = 144 - 64
= 80
Further isolate y by taking the square root of both sides. This will take away the square from the left side
y =
<<< Can be further simplified
4√5 = y
Hope this helped!

A is true, because a parabola is a second degree polynomial, and as such is defined everywhere.
B is true, because the graph of the function never goes below the x axis.
C and D are false because they negate A and B
