Solving Quadratics
What is the name of the graph of a quadratic function?
Factor the expression:
x^2-11x+24
(x-3)(x-8)
What is the vertex of the parabola?
y=-0.5(x+4)2+6
(-4,6)
What is the name of the line that cuts the graph of a quadratic in half?
x^2-x-132
(x-12)(x+11)
What is the equation in standard form?
y=(x+4)^2-1
y=(x+4)(x+4)-1
y=x^2+4x+4x+16-1
y=x^2+8x+15
(0,y)
What is the name of the maximum or minimum of a quadratic function?
25x^2-4
(5x+2)(5x-2)
What is the equation in standard form?
y= -(x-2)(x+10)
y=-(x^2+10x-2x-20)
y=-(x^2+8x-20)
y=-x^2-8x+20
x = -3
2x^2+23x+11
(2x+1)(x+11)
What is the equation of the parabola?
From the vertex we know:
y=a(x-1)^2-2
From the point we know x & y:3x^2+13x-10
(3x-2)(x+5)
Find the vertex of f(x)=x^2-2x
(1,-1)
