Quadratic Situation

For the picture below:
 1) Figure out how many dots in figure 5 and figure 6.
 2) Record coordinate pairs for values -5 to 5 (exactly what you would find in a table).
 3) Write an equation.

6 comments:

  1. 1) Figure 5= 42 dots

    Figure 6= 56 dots

    2) X | Y
    -5 | -8
    -4 | -6
    -3 | -4
    -2 | -2
    -1 | 0
    0 | 2
    1 | 4
    2 | 6
    3 | 8
    4 | 10
    5 | 12

    3) f+1 f+2

    1. Typically we put the parts of the expression in parentheses so that parts that go together are together. So your equation would read (f+1)(f+2).

    2. YEAH, ok but I thought that when they are in parenthesis that you would have to multiply?!?!?

  3. Figure 5: 42 dots. Figure 6: 56 dots.

    X|Y
    -5|-8
    -4|-6
    -3|-4
    -2|-2
    -1|0
    0|2
    1|4
    2|6
    3|8
    4|10
    5|12

    f+1 f=2
