1. For f(x) = x2 and g(x) = (x − 3)2, in which direction and by how many units should f(x) be shifted to obtain g(x)?

2. David kicks a soccer ball off the ground and in the air, with an initial velocity of 35 feet per second. Using the formula H(t) = −16t2 + vt + s, what is the maximum height the soccer ball reaches?

jimthompson5910 (jim_thompson5910):

post one at a time please

OpenStudy (anonymous):

sorry

jimthompson5910 (jim_thompson5910):

hint for #1 when going from f(x) to f(x-h), the graph is shifted |h| units to the right if h is positive when going from f(x) to f(x-h), the graph is shifted |h| units to the left if h is negative

OpenStudy (anonymous):

its positive so...

jimthompson5910 (jim_thompson5910):

yes, the x-h matches up with x-3 h = 3

OpenStudy (anonymous):

ohh ok i got it

OpenStudy (anonymous):

it wouldn't be -3 tho?

jimthompson5910 (jim_thompson5910):

no, think of it as like the opposite h-3 ----> shift 3 units to the RIGHT
