About this lesson
Meet cubic, reciprocal and exponential graphs, learn what an asymptote is, and estimate the gradient of a curve by drawing a tangent. You will learn: • Recognising cubic, reciprocal, squared reciprocal and exponential graphs • Asymptotes: lines a curve gets closer to but never touches • Exponential graphs like y = 2^x • Why the gradient of a curve keeps changing • What a tangent is • Estimating the gradient at a point using a tangent • Practice questions with full answers This is lesson 6 of 7 in Chapter 6: Graphs 6.1 Line segments 6.2 Straight-line graphs 6.3 Parallel and perpendicular lines 6.4 Travel graphs 6.5 Quadratic graphs 6.6 Gradient of a curve (this lesson) 6.7 Graphical solutions of equations © 2026 teachly.lk.
