JavaScript

1) The function "hill" is implemented as follows:

function hill(x) { return -2 * (x - 4) * (x - 16); }

Write a function called quadratic that takes a constant factor and two roots and returns an anonymous function that computes that curve. In other words, quadratic(-2,4,16) should return an anonymous function that behaves the same as hill.

2) The function wrapString(inString, tag) is implemented as follows, so wrapString('foo','em') would return"foo"`:

function wrapString(inString, tag){ return "<" + tag + ">"+ inString + ""; }

Write a function called makeWrapper(tag) that returns a one-argument anonymous function that wraps a string with the given tag.

Write a function called wrapStrings that takes an array of strings and a tag (a string), and returns an array of strings where each is wrapped with the given tag. Use the map() method and the makeWrapper function.
