The standard form of quadratic function.
What is y = ax2 + bx + c ?
The formula of axis of symmetry.
What is x = -b/2a (fraction)?
The y-intercept in y = x2 - 4x- 5.
What is (-5) in y-intercept?
f(x) = 2x2, g(x) 1/3x2 which is more narrower.
What is f(x) is more narrower?
The quadratic function of y + 3x2 = -4. (a = ?? b = ?? c = ??)
What is a = -3 b = 0 c = -4?
The zeros in parabola in y = 1/4x2 + 1. (Yes or No) and why.
What is no of the parabola? The form does not have a parabola because it is +1, so it has one unit up.
The second step after find the axis of symetry to graph a quadratic function.
What is finding the vertex?
The g(x) = 2x2 + 2. How is translated.
What is 2 units up?
The table of y = 2x2 and check if it's a quadraic function.
What is
x | -2 -1 0 1 2
y = 2x2 | 8 2 0 2 8
The value of a and b with y = 2x2 + 4x + 7
What is a = 2, b = 4
The axis of symmetry of y = x2 - 4x - 5
What is 2?
The widest function. f(x) = x2 and g(x) -2x2 + 6
What is f(x)?
What is
minumum = 2
maximum = 5
What is 1?
The step to graph a function. List 5
What is
1. Find the axis of symmetry
2. Find the vertex
3. Find the y-intercept
4. Find more points for same side
5. Graph it
The h1 (t) - -16t2 + 64
h2 -16t2 + 144.
The range of the unit between of h1 and h2.
What is 80 units?
