Best ResponseYou've already chosen the best response.0y=a(xh)^2k @Loser66 ??

Best ResponseYou've already chosen the best response.1yes, but +k, not k and your vertex is ???

Best ResponseYou've already chosen the best response.1ok, so, it is ?? y = ??

Best ResponseYou've already chosen the best response.1Now, pick a point on the graph. (either of them, not vertex)

Best ResponseYou've already chosen the best response.1a point means (.., ...) not just 6

Best ResponseYou've already chosen the best response.1you don't have that point!! , you have (6,0) or (6,0)

Best ResponseYou've already chosen the best response.1which one do you choose??

Best ResponseYou've already chosen the best response.0whoops! um...(6,0) :)

Best ResponseYou've already chosen the best response.1ok, that is x =6 , y =0 right? plug that point into y = ax^2 +36, what do you have?

Best ResponseYou've already chosen the best response.0an upside down parabola / like a rainbow means the value of a is negative

Best ResponseYou've already chosen the best response.1@triciaal please, be patient, it will be there!!

Best ResponseYou've already chosen the best response.1that is 0 = a*36 +36 , right?

Loser66

Best ResponseYou've already chosen the best response.136 both sides, what do you get?

Loser66

Best ResponseYou've already chosen the best response.1no!! redo 0 = a*36 +36 36 36  ??

Loser66

Best ResponseYou've already chosen the best response.1\(0= a*36 \cancel{+36}\\36~~~~~~~\cancel{36}\)

Best ResponseYou've already chosen the best response.1now, divided both sides by 36 , what do you get?

Loser66
 one year ago
Best ResponseYou've already chosen the best response.1\(36 = a*36\\\div 36~~~~~~\div 36\)

Loser66

Best ResponseYou've already chosen the best response.1Now, replace a =1 into the vertex form y = ax^2 +36, you have????

Best ResponseYou've already chosen the best response.0ah! You would get...y=1x^2+36

Loser66

Best ResponseYou've already chosen the best response.1Binnnnnnnnnnnnnnnnngo!! you got it!! can write as y = x^2 +36

Best ResponseYou've already chosen the best response.1@triciaal don't worry about parabola up or down. Apply the standard form, if it is up, we will get a >0, if it is down, we will get a<0.

Best ResponseYou've already chosen the best response.0Wait! Lol we have 1 more part that I don't understand. It's like Part 2 to the question

Best ResponseYou've already chosen the best response.0Create a table of values for a linear function. A drone is in the distance, flying upward in a straight line. It intersects the rainbow at two points. Choose the points where your drone intersects the parabola and create a table of at least four values for the function. Remember to include the two points of intersection in your table.

Best ResponseYou've already chosen the best response.1hahaha... that is supposed to be my question, not yours.

Best ResponseYou've already chosen the best response.1since it is a linear function, that is a line, whatever you like, just "create" it. If I pick y = x, then the line is dw:1437950415171:dw

Best ResponseYou've already chosen the best response.1It will "cut" the parabola at 2 points. dw:1437950461903:dw

Best ResponseYou've already chosen the best response.1If you pick y =x, it is perfectly ok, the line will be here and cut the parabola at 2 points like dw:1437950524706:dw

Best ResponseYou've already chosen the best response.1and the simplest case is dw:1437950561325:dw

Best ResponseYou've already chosen the best response.1still cut the parabola at 2 points. hehehe...

anonymous

Best ResponseYou've already chosen the best response.0but where would the 2 points intersect?

Loser66
 one year ago
Best ResponseYou've already chosen the best response.1but you must choose y =x, since the drone is upward, right?

Loser66

Best ResponseYou've already chosen the best response.1Now, solve for the points you have y =x and y = x^2 + 36 replace y =x x = x^2 + 36 +x^2 both sides, what do you have?

Best ResponseYou've already chosen the best response.0But how would we "create a table of at least four values for the function. Remember to include the two points of intersection in your table?"

Loser66

Best ResponseYou've already chosen the best response.1\(~~~~~~x = x^2 +36\\+x^2~~~~+x^2\)

Best ResponseYou've already chosen the best response.1yes, now 36 both sides

Best ResponseYou've already chosen the best response.1\(x^2+x36 =0\) right?

Best ResponseYou've already chosen the best response.1solve this quadratic, what do you get for x??

Loser66

Best ResponseYou've already chosen the best response.1ok, I put it on my calculator and it gives me x = 5.52 and x = 6.52

Loser66

Best ResponseYou've already chosen the best response.1Take them, now we have the line y =x, and those x values are the intersection of the line and the parabola The Table is just dw:1437951089610:dw
