I need help, but i also want to learn how, not just answers. :) its graphing quadratic equations

Question

asnaseer · Answer

hi - what specifically do you need help on?

anonymous · Answer

okay let me right down the equation :) just a sec...

anonymous · Answer

x^2=-1

anonymous · Answer

how would i go about graphing this?

asnaseer · Answer

ok, so first lets rearrange this to get:$$x^2+1=0$$

anonymous · Answer

okay, so you have to make it equal to zero to graph?

anonymous · Answer

oh! sorry, its -10

anonymous · Answer

my bad

asnaseer · Answer

now the graph of the function:$$y=x^2+1$$ will show you how the function $x^2+1$changes, and, when it equals zero, this will give you a solution to your equation $x^2+1=0$

asnaseer · Answer

thats ok, we just change it to $y=x^2+10$

anonymous · Answer

okay :)

asnaseer · Answer

do you know how to graph this function?

anonymous · Answer

no, I'm not sure

anonymous · Answer

its says sketch graph and axis of symmetry

asnaseer · Answer

ok, let me try and draw it for you and then explain how I got there

anonymous · Answer

For such problems, I would like to typically create a table and then plot those values on a graph. Like the following:

|dw:1322781624348:dw|
