Essential Graphing Formulas Reference Guide

Linear Functions

  • Slope-Intercept Form:
    Y1=mx+b
    m = slope, b = y-intercept
  • Point-Slope Form:
    Y1=m(x-x₁)+y₁
    (x₁,y₁) = point on line

Quadratic Functions

  • Standard Form:
    Y1=ax²+bx+c
  • Vertex Form:
    Y1=a(x-h)²+k
    Vertex at (h,k)

Trigonometric Functions

  • Sine Wave:
    Y1=a*sin(b(x-c))+d
    a = amplitude, b = frequency, c = phase shift, d = vertical shift
  • Cosine Wave:
    Y1=a*cos(b(x-c))+d

Exponential & Logarithmic

  • Exponential Growth:
    Y1=a*e^(bx)
    a = initial value, b = growth rate
  • Natural Log:
    Y1=ln(x)

Graphing Tips & Transformations

Vertical Transformations

  • Y1=f(x) + c → Shifts up c units
  • Y1=f(x) - c → Shifts down c units
  • Y1=c*f(x) → Stretches vertically by factor c
  • Y1=-f(x) → Reflects over x-axis

Horizontal Transformations

  • Y1=f(x - c) → Shifts right c units
  • Y1=f(x + c) → Shifts left c units
  • Y1=f(cx) → Compresses horizontally
  • Y1=f(-x) → Reflects over y-axis
