This is targeted at showing students the relationship between parabolas and straight line graphs (I have included graphs, tables of values and equations so you can pick and choose). The straight line graphs show where the parabola will intersect the x-axis and the symmetry comes out beautifully in the table. Students can think about why the parabola is below the straight line until 1 unit across left or right (think about: half x half = quarter, ie multiplying by a number 0<x< 1 produces an even smaller number)
Blanks have been included if you want to make your own or have students make their own.
Inverse functions - put x in the column where the function for y is and work backwards.
7/11/18 Added same sheet with (x-2)^1 instead of x-2, to focus the shift of a straight line (which can be left/right or up/down) to left and right for the parabola.
Any feedback is welcome - I am going to try this activity later this week.

Great selection of graphical representations of sim equations - ample opportunity to touch base on all sorts of coordinate geometry issues. Thanks for sharing.
