A function is a relation where each input value is assigned to one output value.

The
of a function is the set of all input values, or x-values, for which the function is defined.

The
of a function is the set of all output values, or y-values, for which the function is defined.

To write the equation y = ax + b in function notation, substitute
for y.

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

Anew test for ra is being developed. the test is administered to 750 patients with ra and 750 without ra. for the sake of the question, assume the prevalence of ra in this population is 50%. of the 750 patients with ra, 575 have a positive result. of the 750 patients without ra, 150 have a positive result. what is the positive predictive value of the new test? a575/(575+150) b. 600/(600+ 150) c. 575/(575+125) d. 600/(600+ 125)
