How do you graph quadratic functions

you can plug it into a graphing calcuator right? or no

Step-by-step explanation:

Let's go:

First: You must find the function roots. Function roots are values of y or f(x) when x equals zero.

After this, you use some values of x for find values of y.

And finally, you make the grafic with values founded.

I hope I helped you.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
