1 > x = c(1:10)

2 > y=x^2

The R code above simply creates 2 vectors, x and y, corresponding to values of the function y = x 2 in the domain [1,10]. Use R expressions to write the following:

(a) Four plus the square of x.

(b) The difference of y and x.

(c) The sum of all elements in y.

(d) A vector containing the product of each entry of x with the corresponding entry of y.

(e) The first 5 elements of y (use the facts that a range of values can be written as a:b, and you can access elements of a vector with a call such as v[a : b], where a and b are indices).
