Graphing Functions - Basics

  • Max and min

  • Domain and Range

  • Intercepts,

  • Vertically stretch and compress

Vertex form: y=∣x−h∣2+ky=\left\vert x-h\right\vert^2+k

Vertex: (h,k)

Quadratic Forms - Standard, Factored, Vertex

  • Standard: y=ax2+bx+cy=ax^2+bx+c

  • Factored: y=a(x-r1)(x-r2)

  • Vertex: y=(x-h)+k

Equation of a circle

  • Standard form: (x−h)2+(y−k)2=r2\left(x-h\right)^2+\left(y-k\right)^2=r^2
