Question

graphing quadratics?

Answer 1

I'm confused since those plots aren't on the lines

Answer 2

Working from a chart is fundamentally flawed. Just do the best you can.

This appears to be a parabola with axis of symmetry at x = 2.

Thus, there should be not change at all when considering ONLY the two points at x = 0 and x = 4, no matter what their value appears to be on the odd drawing.

Answer 3

...So it's 0? O.o but why?

Answer 4

What's an Average Rate of Change? If the two points are (0,4) and (4,4), what is the change from 4 to 4?

Answer 5

2 I think? I'm bad at this xD

Answer 6

Average Rate of Change. You must get this concept in your head. It's a lot like SLOPE, but a little more general.

What is the rate of change (the slope) in these two examples?

(0,0) ==> (1,1)

(1,1) ==> (2,3)

Answer 7

0?

Answer 8

the average rate of change between 2 points is the slope.
at x=0, y=4 so the first point is (0,4)
at x= 4, y=4 and the 2nd point is (4,4)

here is a graph of the line through those points

Answer 9

okay..

Answer 10

even though the parabola is zooming down and then back up, the average change between where you started and where you stop is represented by a horizontal line... with slope=0
