10 1) Write an algebraic expression to represent the following verbal expression: The square of a number decreased by the product of 5 and the number 2)Write a verbal sentence to represent the following algebraic expression:

11 The correct response: A number divided by 6 is equal to that number squared.

12 State the domain and range of the relation {(-4, 3), (-1, -2), (0, -4), (2, 3), (3, -3)}. Is this relation a function?

13 The domain is {-4, -1, 0, 2. 3} The range is (-4, -3, -2, 3} Since each member of the domain is paired with exactly one member of the range, this relation is a function.

14 Graph the equation: Label each axis and label at least two points on the line.
