Function ReviewLessons 2.1-2.3

Advanced Math Topics

Mrs. Mongold


Domain and Range

  • Remember basic rules:

    • No negatives in radicals

    • No fractions with 0 as the denominator

  • Linear Functions:

    • In the form y=mx+b

    • Domain is ARN unless it’s vertical

    • Range is ARN unless it’s horizontal

  • Absolute Value:

    • Find corner

    • Domain is usually ARN

    • Range is determined by the y-value of the corner and whether the graph opens up or down

  • Piecewise Functions:

    • Domain and Range are determined solely by the function so you need to look at the graph to determine

      • If you don’t have a graph you need to graph it first!!!


Name the type of function and the Domain and Range for the function

  • f(x)= ½ x – 7

  • f(x)= 3x

    x-14


Name the type of function and the Domain and Range for the function

  • f(x) = √x+11

  • f(x) = √x2 + 6


Name the type of function and the Domain and Range for the function

  • f(x) = |2x + 5|

  • f(x) = 2

    x + 3


Name the type of function and the Domain and Range for the function

x + 3 if x<0

  • f(x) = 5 if x = 0

    2x – 1 if x > 0

    8 if x < -4

    f(x) = x2 + 1 if -4< x < 4

    8 if x > 4


Evaluate the function for the given values f(-3), f(4), and f(a+b)

  • f(x) = -2x + 6

  • f(x) = (x – 2)2

  • f(x) = -x + 112


Write an equation for each function in the form f(x) = mx + b

  • f(-2) = -10, f(2) = 2

  • f(0) = 5, f(7) = 3/2

  • f(1) = 8, m = ½
