Previously, they saw functions whose domain is the integers. Here, they write, interpret, and evaluate exponential functions whose domain is the real numbers. In the second half of the unit, students learn about logarithms in base 2 and 10 as a way to express the exponent that makes an exponential equation true.
Answers will vary. f(x 11. Using your table of values, graph the function. 8 10 10. Using various values for x, make a table of values forf(x) f(x) "Your homework assignment is to graph this function," your math teacher says. She then points to the following function on the board: Ax) x2 2x
Graphing Quadratic Functions and Solving Systems p. 223 Unit Overview This unit focuses on quadratic functions and equations. You will write the equations of quadratic functions to model situations. You will also graph quadratic functions and other parabolas and interpret key features of the graphs. In addition, you will study
identify polynomial, power, rational, trigonometric and exponential functions. Read pages 21-26 of the textbook, and do Exercises 1 and 2 on page 27. do algebraic operations with functions, as explained in the section titled “Combination of functions,” on pages 34-35 of the textbook. Do Exercises 31 and 32 on page 39.
a) Make a graph of a Square Root function with the locator point at (4, 2), and with two other coordinates (5, 4) and (8,6). (4 points) b) Write the equation in graphing (vertex) form.
