Best ResponseYou've already chosen the best response.0For polynomials, the sign of the coefficient determines what way it opens.

Best ResponseYou've already chosen the best response.0The graph is shifted units to the right, 5 units up and vertically stretched by a factor of 2

Best ResponseYou've already chosen the best response.0if i were you mary, I would plot some points (that's probably what you guys are learning)...i'm not sure if what cyter says makes sense to you...good luck

Best ResponseYou've already chosen the best response.0take the second derivative of y or d²y/dx², if its positive, then the graph is concave up on an arbitrary interval (a,b)

Best ResponseYou've already chosen the best response.0i now have to determine whither this point is wider or narrower. \[y=(x4)^{2}+5\]

Best ResponseYou've already chosen the best response.0The utmost easiest way to determine whether a graph of a polynomial opens up or down is to look at the leading coefficient, which is the coefficient in front of the x^2. If that coefficient is positive the graph opens up, if negative it opens down.

Best ResponseYou've already chosen the best response.0oh ok. oops i typed the same problem. this is the equation I need to figure out if it is wider or narrower than the previous one..\[y=2(x4)^{2}\]

Best ResponseYou've already chosen the best response.0i think it's narrower

Best ResponseYou've already chosen the best response.0The higher the magnitude of the coefficient, the narrower the graph is. You are correct.
