Question

Students in Mr. Mackie's art class went outside to draw a rainbow, whichfollows a parabolic path and has the equation of y = -0.1 (x - 1)^2 + 6, where y and y are measured in centimeters. Graph the function.

If the height of the rainbow is 6cm, how far away are the end points of the rainbow from one another?

(An explanation would also help a lot!)

Answer 1

15.492cm

Explanation:

To graph you input numbers and find the other variable.

EG you put x=0, and then solve y according to that.

And then you look at the end points which are (-6.746,0) and (8.746,0)

So distance is 15.492
