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!
