    Study Notes

    Number of Solutions to Linear Equations

    • Possible outcomes include no solution, one solution, or infinite solutions.
    • Graphically, each solution represents the intersection points of lines.

    Forms of Equation for a Line

    • Various forms include slope-intercept, point-slope, and standard form.
    • Parallel lines have equal slopes; intersecting/perpendicular lines have slopes that are negative reciprocals.

    Key Features of Inequalities and Graphs

    • Multiplying/dividing by a negative flips the inequality sign.
    • Dotted lines represent strict inequalities (below/above), while solid lines indicate inclusive inequalities (includes the line).
    • For multiple inequalities, the solutions satisfy all conditions simultaneously.

    Factoring Quadratic and Cubic Functions

    • Common methods for quadratic functions include factoring, completing the square, and quadratic formula.
    • Cubic functions can often be factored by grouping or synthetic division.

    Critical Points and Features for Graphing

    • Y-intercept: Found by setting x to 0.
    • X-intercept(s): Found by setting the function to 0.
    • Domain: The input values where the function is defined; undefined for division by 0 or imaginary results.
    • Range: The resulting output values of the function.
    • Consider end behavior and vertical asymptotes when analyzing the function's graph.

    Relation of Pythagorean Theorem to Other Concepts

    • The Pythagorean theorem (a² + b² = c²) links to the distance formula and is foundational in deriving trigonometric identities.

    General and Standard Form Equations

    • Line: y = mx + b
    • Absolute value: y = |x|
    • Quadratic: y = ax² + bx + c
    • Cubic: y = ax³ + bx² + cx + d
    • Exponential: y = ab^x
    • Logarithmic: y = log_b(x)
    • Rational: y = p(x)/q(x)
    • Radical: y = √x
    • Sinusoidal: y = A sin(B(x - C)) + D
    • Circle: (x - h)² + (y - k)² = r²

    Transformations and Properties

    • Dilation: Changing size proportionally.
    • Rotation: Pivoting around a fixed central point.
    • Translation: Shifting a figure without altering its orientation.
    • Reflection: A mirrored counterpart across a line.
    • Similarity: Identical shapes with proportional dimensions.
    • Congruency: Identical shapes and sizes.

    Perimeter and Area Formulas

    • Rectangle: Perimeter = 2(l + w), Area = l × w
    • Trapezoid: Perimeter = sum of all sides, Area = ½(b₁ + b₂)h
    • Circle: Perimeter (Circumference) = 2πr, Area = πr²
    • Cylinder: Surface Area = 2πr² + 2πrh, Volume = πr²h
    • Sphere: Surface Area = 4πr², Volume = (4/3)πr³

    Asymptotes and Undefined Portions

    • Vertical asymptotes arise from equation settings that involve division by zero.
    • Horizontal asymptotes relate to the degrees of polynomials in the numerator and denominator.
    • Undefined portions also occur in radical functions with negative values leading to imaginary results.

    Operations on Functions

    • Addition, subtraction, multiplication, and division of functions can create new functions.
    • Composition of functions is another fundamental operation.

    General Forms of Function Types

    • Linear: y = mx + b
    • Absolute Value: y = |x - h| + k
    • Quadratic: y = ax² + bx + c
    • Cubic: y = ax³ + bx² + cx + d
    • Exponential: y = ab^x
    • Logarithmic: y = log_b(x)
    • Sinusoidal: y = A sin(B(x - C)) + D

    Properties of Exponents and Logarithms

    • Exponent rules include multiplication (add exponents), division (subtract exponents), and raising to a power (multiply exponents).
    • Logarithmic properties encompass the product, quotient, and power rules, linking them to their corresponding exponential forms.

    Law of Sines and Law of Cosines

    • Law of Sines: a/sin(A) = b/sin(B) = c/sin(C) for any triangle.
    • Law of Cosines: c² = a² + b² - 2ab cos(C) relates side lengths to angles in a triangle.

    Major Trigonometric Functions

    • Functions include sine, cosine, and tangent, with respective opposite, adjacent, and hypotenuse side lengths related to angles in right triangles.
