  • Unit 1 Day 1 Notes: Name:______________________ Graphing Equations of Lines & Function Notation Date:______________ SLOPE INTERCEPT FORM OF A LINE:_______________________

    What is the equation of the line in the graph displayed below:

    Let’s graph the equation 1 2 3

    y x

    Slope:______ Y-Intercept:_______

    Domain:_________________ Range:__________________

    Let’s graph the equation 2 4y x .

    Slope:______ Y-Intercept:_______

    Domain:_________________ Range:__________________

    Let’s graph the equation 2 3 6x y .

    Remember it MUST be in slope intercept form in order to graph!

    Slope:______ Y-Intercept:_______

    Domain:_________________ Range:__________________

    Slope:_____ Y-Intercept:____

    Equation:___________________

    Write the slope as a fraction & y-intercept as a point!

  • Let’s practice putting equations in slope-intercept form (SOLVE FOR Y!!). Then state the slope and y-intercept.

    10 3y x Slope:_____ Y-Intercept:____

    3 4 12x y Slope:_____ Y-Intercept:____

    2 7 14x y Slope:_____ Y-Intercept:____

    Graph a Vertical line: Graph a Horizontal line:

    Find 3 points on your line: Find 3 points on your line:

    WHAT DO YOU SEE? WHAT DO YOU SEE?

    Equation of your line: Equation of your line:

    Using FUNCTION NOTATION

    Given f(x) = x2 – 2, find: f(5)= f(-5)= f(0)=

    Given g(x) = 2x + 7, find: g(4)= g(-4)= g(a)=

    Given h(x) = -2x2+ 7x - 11, find: h(2)= h(2a)= 3h(-3)=

    A little more of a challenge: Given f(x) = 2x + 1, find -4[f(3) – f(1)].
