• Give specific techniques for each type of function and clarify how the domain and range are expressed. It is not sufficient to state that the domain is the x-values and the range is the y-values. There are example problems listed with each type of function. Clearly organize the posting by referring to A, B, and C.

A) How do you determine the domain and range of a function expressed with a graph? In section 2.2, #54b and #58a are functions expressed with a graph.

B) How do you determine the domain and range of a function expressed with a set of ordered pairs? In section 2.1, #26 is a function expressed with a set of ordered pairs.

C) How do you determine the domain and range of a function expressed with an equation? In section 2.2, #18 and #24 are functions expressed with an equation.

• Each teacher at C. F. Gauss Elementary School is given anacross-the-board raise of $4200. can you find a function that transforms each old salary x into a new salaryN(x). N(x)=

• Solve the inequality by graphing an appropriate function. State the solution set using interval notation.

(x+5)29<0

Graph the appropriate function

• Shown on the grid is a graph of y=|x4|4. Use a graph to solve the inequality|x4|-4>0

• Solve the inequality x²10 by reading the corresponding graph y=x²1.

• Write the equation of the graph after the indicated transformation.

The graph of y=|x| is reflected in thex-axis, stretched by a factor of 2, then translated 5 units to the left and up 4 units.

What is the equation of thefunction?

• Write the function whose graph is the graph of y=x², but is translated 3 units to the left and 4 units upward. y=

• Write the function whose graph is the graph of y=x², but is translated 6 units to the left. y=
