Students were asked to answer a question at education and to indicate what is most important for them to succeed. The one that response stood out from the rest was practice. Successful persons are definitely not born successful; they become successful with hard work and persistence. This is how you can get your goals. in the following paragraphs are one of the answer and question example that you could actually utilize to practice and upgrade your knowledge and also give you insights that may assist you to sustain your study in school.
What is the equation of the graph below? A graph shows a parabola that opens down with a vertex at three comma one. y = − (x − 3)2 + 1 y = − (x + 1)2 + 4 y = (x + 1)2 − 4 y = (x − 4)2 + 1
The option must be:
There are generally two forms in which quadratic equation is represented:
The options here are given in the second form, so by interpreting the second form in graphical form will give the the answer.
In second form ‘h’ and ‘k’ are the x-coordinate and y-coordinate respectively of the vertex of parabola.
In the given graph the coordinates of vertex is (3 , 1).
So h = 3 and k = 1.
In the second form ‘a’ decide the direction of opening of parabola, if a is greater than zero than the opening is upward and if a is less than zero than opening of parabola is downwards.
In the given graph the parabola opens downward so the value of a is -1.
a = -1
Therefore the final equation of parabola is as follows:
They will possibly hopefully guide the student deal with the question by implementing the questions and answer examples. Then may carry out some sharing in a group discussion and also study with the classmate with reference to the topic, so another student also possess some enlightenment and still keeps up the school learning.
