This is the word that describes where a graph crosses the Y-AXIS.
Y-INTERCEPT
100
Solve: l/ -9=
= 3i
100
Solve: 2i+3i=
= 5i
100
What is i to the first power?
=i
200
2+3i +4+7i solve the above
= 6 + 10i
200
What does the 'i' stand for in math?
Imaginary.
200
Solve: l/-36=
= 6i
200
Solve: 16i-5i=
= 11i
200
What is i to the second power?
= -1
300
What is i to the 40th power?
40/4 = 10 with Remainder 0 so i^40 = i^0 = 1
300
What are the two words to describe whether a parabola is flipped upside down or up?
CONCAVE UP CONCAVE DOWN
300
Solve: l/-25=
= 5i
300
Solve: (2+4i)(3-5i) using the BOX METHOD. Remember i^2 = -1
= (2+4i)(3-5i) = 6 + 12i - 10i + 20i^2 <--- TERMS FROM BOX METHOD = 6 + 2i + 20(-1) <-- REPLACE i^2 WITH -1 = 6 + 2i - 20 <-- Combine like terms. = -14 + 2i <-- FINAL ANSWER
300
Solve: 3i * 2i Remember i^2 = -1
= 6i^2 = 6(-1) = -6 <--- Final Answer.
400
(2+3i) (4+7i) solve the above USING BOX METHOD Remember: i^2 = -1
(2+3i) (4+7i) = 8 + 12i + 14i + 21i^2 <-- Box Method Terms = 8 + 26i + 21(-1) <-- Replace i^2 with -1 = 8 + 26i - 21 <--- Simplify and combine like terms. = -13+26i <--- FINAL ANSWER
400
What is the line called that goes exactly in the middle of a parabola and intersects with the vertex?
AXIS OF SYMMETRY
400
Solve: 3+2xi - (4 + 6xi)
= 3+2xi - 4 - 6xi <-- Distribute the negative = -1 - 4xi <--- Combine Like Terms.
400
Solve: l/ -49=
= 7i
400
Simplify so that there is no 'i' in the final answer (-5i)^3
= -5i * -5i * -5i = -125i^3 = -125 (-1) = 125 <--- FINAL ANSWER.
500
Using x = -b/2a, find the axis of symmetry for: y = 4x^2 +7x - 3
a = -3 b = 7 so x = -7/2(3) = -7/6 <-- final answer
500
Draw a representation of what it means to be ONE TO ONE
Teacher will look at boards to determine credit. DO NOT ERASE, DO NOT CHEAT!!
500
Solve: l/-18=
l/-18 = l/-9 * l/2 <- Break -18 into perfect and non-perfect # = 3l/2i <-- Final Answer.
