This paper studies the problem of optimal estimation of a quadratic functional of two normal mean vectors, $Q(\mu ,\theta )=(1/n)\Sigma ^n_{i=1}\mu ^2_i\theta ^2_i ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...

Practice how to recognise and determine the equation of a quadratic function from its graph ahead of your National 5 Maths exam with this interactive maths quiz. The equation of a a quadratic function ...

Bodily functions rise and decline with age, and the brain is no exception. However, the exact trajectory of our brain activity during controlled behavior remains unclear. A recent study published in ...
