Need some help with a few question.
1. Determine whether the relation is a function. Find the domain and range.
{(10,2),∙(10,2),(6,4),(5,3),(6,7)}
2. What is f(4) if f(x) = 3x + 4  2
3. Write an equation that defines the graph of y = x2 after it is shifted vertically 2 units up and horizontally 3 units left.

3. new vertex is (3,2)
... y = (x  3)^2 + 2
2. f(4) = 3(4) + 4  2
1. looks okay for vertical line test
... domain ... xmin to xmax
... range ... ymin to ymax
