A function machine is a way of writing rules using a flow diagram. The equation \(3h - 6 = 9\) can be shown on a function machine by writing out the functions that have been applied to \(h\) in the ...

A function machine is a way of writing rules using a flow diagram. The equation \(3j - 6 = 9\) can be shown on a function machine by writing out the functions that have been applied to \(j\) in the ...

A new equation for calculating a person's kidney function — their estimated glomerular filtration rate (eGFR) — worked as well with serum cystatin C as it did with serum creatinine as the biomarker.

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

Earlier equations for kidney function were derived exclusively from White people and did not consider race. The finding of decreased accuracy in Black Americans later prompted researchers to introduce ...
