Polynomials
x2 - x - 12
This symbol is represented by a dot in later maths, and an X in earlier maths. What is it?
Multiplication
If a line passes through (0,3) and (5,8), what is its formula?
Hint: Y = mx + b
y = x + 3
What is an angle that is exactly 90 degrees?
Right angle.
A shape has 4 sides, 4 90 degree angles, and 2 sides that are longer than the other. What is it?
A rectangle.
Simplify: (2x + 3)(x + 1)
2x2 + 5x + 3
This operation often makes irrational numbers. What is it?
Square root
y = -x - 3
This angle is bigger than 90, but less than 180. What is it?
This shape has 8 sides, and it's angles add up to 1080 degrees. What is it?
A octogon.
Simplify: (x2 + 3)(x + 10)
x3 + 10x2 + 3x + 30
This operation creates a sequence of numbers that go from it all the way to 1. What is it?
Factorial.
A line passes through (-2, 5) and has a slope of -3. What is it's y intercept?
11
This angle is smaller than 90 but bigger than 0. what is it?
Acute angle.
This shape has 3 sides, none of them are the same angles, and they add up to 180 degrees.
Scalene Triangle.
Simplify: (3x - 2)(-x + 3)
-3x2 + 2x - 6
This operation does have a symbol, but it is rarely used in higher maths. What is it?
Division.
A line has a y intercept of 11 and passes through the point (2, 15). What is it's slope?
.5
What is an alternative name for the point (0,0)?
The Origin.
This shape has 0 sides, but is 2 dimensional. What is it?
Hint: what shape are most pies?
Circle
Simplify: (-3x + 3)(-2x - 7)
6x2 + 15x - 21
This operation makes INSANELY large numbers extremely quickly. What is it?
Tetration (looks like this yx), which is a tower of x's of y height.
If a line passes through (-3, 4) and (5, -5), what is the formula for it?
Hint: Y = mx + b
y = -1.125x + 0.625
If a function has two or more points on the same y coordinate, it fails this test. What is this test called?
Vertical line test.
This shape extends forever inward, and is made out of purely triangles. What is it?
Hint: This shape has 1.58 dimensions.
