f(x)=-x^2-2x+3 is theequation I want to graph.
Ok first we need to find the axis ofsymmetry.
It is a vertical line that passes through the vertex of a parabola the divides it into two congruent halves.
Ok so now how do we find the vertex?
Remember how I told by finding the axis of sym. we would find the x value of the vertex now we need to plug in that x value into the equation so justsubstitute!
Lets walk on the way because we have to get home.
I found my y-value!
Ok now take your x value from axis of symmetry and put it together with the y value to make acoordinatethat's your vertex!
Oh wow that was easy
But were not done yet we need to find the y-intercept.
I think I heard my teacher say to find the y-intercept we need to make x=0 is that right?
Yeah that's right, you canactually listen!
I was just playing with you.
Hey that's not funny!
Now you find the x-intercept by plugging y in as 0
I got it and I plotted on the y-intercepton both sides equallyseparatefrom each other.
Just like the y-intercept but with y as 0.
Yup just the same thing but there is a trick you can use vietas method
Oh yea Ms.Beard taught me that
There's nothing like being at home.
I found everything and plotted it what do I do now?
Now you need to draw it through all the points to make a U shape.
I drew a line since the graph is facing downwards would it be a maximum?
Correct you just graphed your first quadratic formula!
