Suppose in 1970 there were 1.3 million college degrees awarded. This number increased to 2.5 million in 2010. (a) Find a linear function D that approximates degree
numbers in millions x years after 1970.
(b) Interpret the y-intercept on the graph of D.
(c) Estimate symbolically when this number was 2.2 million.
(a) D(x) =
(Use integers or decimals for any numbers in the expression.)

What kinds of numbers make up the set of numbers called the real numbers? give examples when you explain a number type. there are a limited set of types of numbers, but an unlimited number of examples of these numbers.
