|10x-2| = |10(x - 1/5)|-7
so, what do you think?
the vertex of ax^2+bx+c is at x = -b/2a
Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of the given function?
y= |10x-2|-7
A. (1/5,-7); x = 1/5; translated to the right 1/5 unit and down 7 units.
B. (1/5,-7); x = 1/5; translated to the left 1/5 unit and up 7 units.
C. (1/5,7); x = 1/5; translated to the left 1/5 unit and down 7 units.
D. (1/5,7); x = 1/5; translated to the right 1/5 unit and down 7 units.
Every year in Delaware there is a contest where people create cannons and catapults designed to launch pumpkins as far in the air as possible. The equations y = 12 + 105x - 16x^2 can be used to represent the height, y, of a launched pumpkin, where x is the time in seconds that the pumpkin has been in the air. What is the maximum height that the pumpkin reaches? How many seconds have passed when the pumpkin reaches? (hint if the pumpkin hits the ground its height is 0 feet.)
