Consider a regression problem with examples described by 2 continuous attributes, x and y. each example is sampled according to the uniform distribution on (−1,1)2 and labeled with f(x, y)=1−x2−y2. a learner’s hypothesis class is h(x, y)=ax+by+c. calculate its bias and variance as a function of x and y if the learner sees an arbitrarily large training sample.

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
