Question 23010: last question. I have a problem figuring out how to graph the quadratic function. I need to understand how to do this can someone explain it to me please. thank u very much. the question says begin by graphing the standard quadratic function f(x)=x^2. The use transformation of this graph to graph the given function. g(x)=-1/2(x-3)^2-3 i am not understanding it. Help please

Question 21540: I could use help on learning whare to place ordered pairs in quadratic equations. I have been ought for a long time because of a illness, so any help is greatly appreciated. my teacher asks : Given the points on the graoh, find the particular equation of the quadratic function containing the given ordered pairs, write the equation in standard form y=ax^2 + bx + c.............
One set of ordered pairs I am given is : (1,6),(3,26),(-2,21).......Thanks for the help, peter

Question 21167: sorry,the 1st letter had some mistakes. hi.I have a question how can you find the coordinates of the vertex.Make a table of values,using x-values to the left and to the right of the vertex.
1.y=3x^2
how can we now "b" and "c" with this kind of equation.there`s no graphs sktechings.
Thank you.

Question 23274: Maximum cost using the quadratic equations, functions, inequalities and their graphs. It costs Acme Manufacturing C dollars per hour to operate its golf ball division. An analyst has determined that C is related to the number of golf balls produced per hour, x, by the equation C = 0.009x^2 - 1.8x + 100. What number of balls per hour should Acme produce to minimize the cost per hour of manufacturing these golf balls?

Question 23273: We are working with quadratic functions and their graphs. The question is: If a baseball is projected upward from ground level with an initial velocity of 64 feet per second, then its height is a function of time, given by s(t) = -16t^2 + 64t. Graph this function for 0 < or equal to t < or equal to 4. What is the maximum height reached by the ball?
