I hope this helps you
x=3
f (3)=4.3^2-8.3+3
f (3)=36-24+3=15
f (3)=4.3^2-8.3-3=36-24-3=5
This is a proportional relationship. So any example that shows as x increases, y decreases.
A real life example would be where
x=time i let the pool drain
y=amount of water left over
As I let the time I let the pool drain increase, the amount of water left in the pool decreases.

30 there u go
that the rounding
Use a^2 + b^2 = c^2
the triangle must be isosceles because the two angles are the same
1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706
