First Partial Math Topics
Function and Relations
Distance: the measure between two coordinates
Midpoint: The place where two lines meet
Numerical Line: a straigth line that helps you to graph when in a function you only have a variable.
Interval: example (1,9)
Continuous Function: When the values in a set are later not separated in Cartigian planes, or numerical line.y
Discrete Function: When the values in a set are distinct and separate
Vertical and Horizontaal Lines
PA Point: (-x,∞)
No y intercept
Domain: All real numbers
Range is written in keys
Points are written like (-∞,∞)
Domain and Range: (∞,∞)
The values to solve are x and y
Systems of Equations
General form: Ax+By+C=0
Types of system
Solving for linear equations
Answer for closed question: NO
Answer for clOse question: YES
Parallel lines: You keep your slope but change the y intercept
Perpendicular line: You change the slope to its reciprocal and change the sign, as for the y it doesn't matter
The steepness of the line, its always constant and doesn't change.
Whats the value of y when x is 0
Absolute value: how far a number is from zero
