# Algebra

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.

1. 0
2. 2
1. 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
