Graphing
What is the domain of a relation? What is the range of a relation?
Domain is all the X coordinates.
Range is all of the Y coordinates.
(a + 2)(a + 4)
a2 + 6a + 8
6x2y + 2x
2x(3xy + 1)
What does Congruent mean?
The exact same side lengths and angles.
What quadrant is (-8, 5) in?
Quadrant 2
(x - 7)(x - 1)
x2 - 8x +7
12x2 + 4x
4x(3x + 1)
What does similar mean
Side lengths are Proportional and angles are the exact same.
What quadrant is (4, -2) in?
Quadrant 4
(x + 4)(x - 4)
x2 - 16
x2 + 6x + 8
(x + 2)(x + 4)
What is the Pythagorean Theorem.
a2 + b2 = c2
How can we tell if a relation is a function?
Straight line test or the Xs do not have more than one Y.
(x - 2)(x +5)
x2 + 3x - 10
(x + 6)(x - 2)
If a = 7 and b = 24 what is the length of the hypotenuse (c)?
25
What is a U shaped curve called?
Parabola
(3m + 4)(2m - 5)
6m2 -7m - 20
x2 - 25
(x + 5)(x - 5)
If a = 3 and c = 5 find the side length of b.
4
