Some ways to describe the function is that it has a narrow, upward faceing parabola. The x-intercepts are (5,0) and (-2,0). The y-intercept is (0,-10) and it has an absolute minimun.

I see many people commenting first, but the first to comment was Emma. Anyway, this was good review. Please start coming to tennis practices, Mr. Bigsby. You are a very good tennis player.

Ways to describe the function:
Narrow
Faces upward
Zeros/ x- intercepts- (5,0)(-2,0)
Y-intercept- (0,-10)
Vertex- (1.5, -122.5)
Axis of Symmetry- x=1.5

Thanks. The parabola is upward and narrow because 10 is a big number and it is positive too. The x intercepts/zeros are (5,0) and (-2,0). The y intercept is (0,-100) I think.

Zeros/ x- intercepts- (5,0)(-2,0)
Y-intercept- (0,-10)
Vertex- (1.5, -122.5)
Axis of Symmetry- x=1.5

X-intercept= (5,0), (-2,0)
Y-intercept= (0,-100)
It a polynomial.

this video was super helpful! some ways to describe the parabola would be narrow, and it faces upward. thanks so much! btw i love carcassonne so much, me and my dad play it all the time lol

Sian, I was going to type the exact same thing about being "first".


(function description)
x-intercepts=(5,0)(I got 2,0, I'll need to recheck),
polynomial

Okay, I actually have no idea how the keyboard changed the language when it was English 3 seconds ago.

Gotta Thank EPIC GRAPH BATTLES OF ALGEBRA - QUADRATICS For these
1.Extremely Narrow.
2.Upwards.
3.Zeros/X-intercept....5 and -2
4.Y Intercept -10
5.Polynomial
6.Vertex 1.5, -122.5
7.Axis of Symmetry 1.5
8.Curved
9.Passes Vertical Line Test. (if its a quadratic, it obviously passes)
10.Decreases Then Increases.

This was a good refresher after learning about vertex form I forgot a lot of things about factored and standard form.
