# Learn how to sketch the graph of a function using Calculus techniques

## Key Points

Curve sketching refers to sketching the graph of a function

Curve sketching relies on finding key points on the graph of a function

Key points include the X & Y intercepts and the stationary points

The X intercept is found by letting y = 0 and solving the resulting equation

The Y intercept is found by letting x = 0 and solving the resulting equation

Stationary points are found by setting the derivative equal to zero and solving the equation

The ‘nature’, or type, of stationary point is determined using a nature table or 2nd derivative

The key points should fit together on the sketch to produce a coherent graph
