What does the graph of f(x)=x^2 look like if it is negative make sure to include shape and direction?

see the explanation

Step-by-step explanation:

we have

This is the equation of a vertical parabola open upward

The vertex represent a minimum

The vertex is the point (0,0)

The general shape of a parabola is the shape of a "pointy" letter "u," or a slightly rounded letter, "v."

If the function is negative

then

This is the equation of a vertical parabola open downward

The vertex represent a maximum

The vertex is the point (0,0)

see the attached figure to better understand the problem

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
