Best ResponseYou've already chosen the best response.01. 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)?

Best ResponseYou've already chosen the best response.1hint for #1 when going from f(x) to f(xh), the graph is shifted h units to the right if h is positive when going from f(x) to f(xh), the graph is shifted h units to the left if h is negative

Best ResponseYou've already chosen the best response.1yes, the xh matches up with x3 h = 3

Best ResponseYou've already chosen the best response.1no, think of it as like the opposite h3 > shift 3 units to the RIGHT

Best ResponseYou've already chosen the best response.1what's really going on is the entire xy axis is being shifted 3 units to the left, the f(x) stays still giving the illusion it's moving 3 units to the right

Best ResponseYou've already chosen the best response.0oh so would the answer be B or A? @jim_thompson5910

Best ResponseYou've already chosen the best response.1`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?` what are `v` and `s` in this case?

jim_thompson5910

Best ResponseYou've already chosen the best response.1so `H(t) = 16t^2 + vt + s` turns into `H(t) = 16t^2 + 35t + 0` which is really `H(t) = 16t^2 + 35t`

Best ResponseYou've already chosen the best response.0how do i solve without t though?

jim_thompson5910

Best ResponseYou've already chosen the best response.1I'm going to replace every t in ` 16t^2 + 35t + 0` with x so we have ` 16x^2 + 35x + 0`

jim_thompson5910

Best ResponseYou've already chosen the best response.1do you see how ` 16x^2 + 35x + 0` matches up with `ax^2 + bx + c` ?

Best ResponseYou've already chosen the best response.0So would we plug in the max and min which would be 35 and 32 to the x's?

Best ResponseYou've already chosen the best response.0H(t) = 16(35/32)² + 35(35/32) = 19.141 which would be closest to D. Ok did i do it correctly?

Best ResponseYou've already chosen the best response.1are you familiar with the formula h = b/(2a) ??

jim_thompson5910

Best ResponseYou've already chosen the best response.1so you'll plug a = 16 and b = 35 into that formula to find h

jim_thompson5910

Best ResponseYou've already chosen the best response.1tell me what h is

jim_thompson5910

Best ResponseYou've already chosen the best response.1oh nvm, you already found h when you said 35/32

Best ResponseYou've already chosen the best response.1`H(t) = 16(35/32)² + 35(35/32) = 19.141` looks good

jim_thompson5910

Best ResponseYou've already chosen the best response.1except that I get 16(35/32)² + 35(35/32) = 19.140625
