Question 3010: How do you find the domain and range of a quadratic equation??? And if I were to get a complex root from -40+/-the square root of negative 1472 all over 32. Would my X= -40+/- 8the square root of 23i all over 32? And if so, what are the steps to getting there???

domain is basically all the valid numbers you can put into an equation without it breaking...the x-values

range is that set of number you get out of the equation if you put all the values of the domain into it...the y-values.

Now to simplify the 1472...2*736....4*368... 16*92... 64*23...we have a square root, so look for a number that will have a nice root, like 4, 9, 16, 25, 36, 49, 64 etc

so can be written as which is which is

So, our calculation now becomes: which is what you said, and this can simplify a little further to which is
