2.  Equations that represent functions are often written in function notation.  f(x) is used in place of y in function notation.  y = mx + b becomes f(x) = mx + b  If I want to evaluate for a number, I can plug the number in for x  f(#) means to plug the # in for x in order to evaluate.  ***can use other letters. For example g(x), h(x),…

3.  Evaluate the function y = 3x + 2 for x = -2, 0, and 3  X = -2:  X = 0:  X = 3:

4.  Evaluate the function f(x) = 3x + 2 for x = -2, 0, and 3  X = -2:  X = 0:  X = 3:

5.  Evaluate when x = 4  f(x) = 3x – 2  g(x) = -2x + 7  h(x) = ½x - 5

6.  Given y = 3x + 4, find the value of x so that y = 10

7.  Given f(x) = -2x+10, find the value of x so that f(x) = -6

9.  A family of functions is a group of functions with similar characteristics. For instance, linear functions of the form g(x) = mx + b is a family of functions. The most basic form of this equation is f(x) = x. This is called the parent function.
