Best ResponseYou've already chosen the best response.0based on the graph, I'd say the function itself is \[\frac{ 1 }{ 3 }x ^{2}\]

Best ResponseYou've already chosen the best response.4ok, after rereading they are asking about the "a" value I assume they mean, if we write the equation in the form y= a(xh)^2 + k they want the "a"

phi

Best ResponseYou've already chosen the best response.4(h,k) is the vertex (the lowest point) and for your parabola, the vertex is (0,0) that means h=0 and k=0 and the equation is y = a(x0)^2 + 0 and that simplifies to y= a x^2 to find a, put in an (x,y) pair that is on the parabola. For example, try using (3,3)

Best ResponseYou've already chosen the best response.0@phi , nice catch! I completely missed the "a" in the problem. It makes much more sense now :)

Best ResponseYou've already chosen the best response.0I would definitely use the point (3,3) since it's the only point that is clearly at an intersection of 2 whole numbers. Just plug it into the equation and solve for a. \[y=ax ^{2}\]\[3=a \times3^{2}\]\[3=a \times9\] finish it out and you're done!

Best ResponseYou've already chosen the best response.0im still confused..i been sitting here trying to figure this out..

Best ResponseYou've already chosen the best response.0Use the vertex form for finding the equation of a parabola. @phi already provided this... (h,k) is the vertex, which for the graph you provided is (0,0). Pick a point that is easy to identify like (3,3) and plug it into the vertex form equation. \[y=a(xh)^{2}+k\]

Best ResponseYou've already chosen the best response.0Plug in what you know... Given the point (3,3), y=3 and x=3. Given the vertex (0,0), h=0 and k=0 you end up with the equation below...just solve for "a" \[3=a(30)^{2}+0\]

Best ResponseYou've already chosen the best response.0@phi definitely deserves it for catching the part we were all missing in the original problem!

Best ResponseYou've already chosen the best response.0I gave it to @phi, but @stacy.reed08 i have more confussing ones that i could use some help one.
