Question 86475: Hello I need to know how to complete:
Graph the equation y=x(squared) + 2
thanks
Answer by chitra(359)  (Show Source):
You can put this solution on YOUR website! The given equation is y = x(squared) + 2
==> y = 
The given equation is a quadratic in "x". The graph of any quadratic equation will always be a parabola.
Hence, the graph look like this:
Hence, the solution..
This can also be worked in another way...
Let f(x) =
Given the equation just plug in the values for x and then make the table for x and f(x). Then plot all these points on the number line along the co-ordinate axes...
For example when x = 0, f(x) = 2
x = 1 , f(x) = 3
x = 2 . f(x) = 5
x = 3 , f(x) = 10
And similarly for the negative values..
x = -1 , f(x) = 3
x = -2 , f(x) = 5
x = -3 , f(x) = 10
f(x) will have the same values, since the given function is an even function..
Thus, the solution...
