Factoring & CTS
How many terms does slip and slide have?What is is called?
What is 3-trinomial
What is the shape of a quadratic function?
What is: parabola or u-shape
Can you use the formula for any quadratic function?
What is: yes
What is the vertex form? say or write it out
What is: f(x)=a(x-h)2+k
When does the graph have a maxima?
What is: when the a-value is negative.
True or False. The first step when solving quadratics is tp look for the number of terms.
What is False- Look for GCF
What is standard form?
What is: f(x)=ax2+bx+c
How do you find the vertex using standard form?
What is: (-b/2a, f(-b/2a))
How do you you reflect the graph over the x-axis?
What is when a is negative or a<0
How do you find the vertex using vertex form?
What is: use the point (h,k)?
True or False. Guess and check only works for functions with a leading coefficient of 1.
What is False. It works for slip and slide and binomials(difference of squares).
What is the max number of answers you can get in quadratics?
2
What is the quadratic formula? Say or write the equation
[-b±√(b^2-4ac)]/(2a)
Name all transformations: f(x)=(x-4)-10
What is: right 4units and down 10 units
What are the x-intercepts of f(x)=2x2-10x+72
What is: (x-9)(x+4) -> x=+9,-4
What are the groups and factors for this?
9x2+3x-24x+8
What is: 3x(3x+1)-8(3x-1)
True or False. Only vertex form has a vertex and standard form does not have a vertex.
What is Flase
What are the three types of answers you can get from the discriminant?
What is: b2-4ac >0:2 real numbers
<0:2 imaginary/complex numbers
=0:1 real number repeated twice
What is the function if the parent function is moved 4 units to the left, 7 units up and has a horizontal stretch of 4.
What is: f(x)=1/4(x+4)2+7
What is the end behavior of f(X)=-2(x+6)2-7?
What is: as x->-infinity then f(x)->-infinity
as x->+infinity then f(x) -> -infinity
What number should be used to complete the square?
x2-14+__=28
What is 49?
Why can quadratic functions NOT be rotated 90 degrees?
What is: it will fail the vertical lines test in most rotations.
What is the answer for: f(x)=2ax2+8x-2
What is: -2±√5
Name all transformations: f(x)=-1/2(x+7)2+3
What is: reflect over x-axis, h-stretch by 2, left 7, up 3
What is the Domain and Range of f(x)=(x-2)2+5
What is domain: all real numbers (-infinity,+infinity). Range: [5,+infinity)
