How to solve quadratics graphically

Find where it crosses the X axis

Quadratic graph

y = x² + ax + b is a U graph / if -x² than it is a n graph

Exponential graph

y = k ^x - big swooping curve that never falls below x axis and increase rapidly in the y direction

Reciprocal graph

y = 1/x - two curves that are symmetrical at a diagonal on opposite squares

Cubic graph

y = x³ + n - they go up rapidly then straighten then continue increasing rapidly
