Cubic, reciprocal and other curves
Pages
Cubic graphs
The S-shaped curve of x³, and how a negative coefficient flips it.
Reciprocal graphs
The two branches of y = 1/x, approaching but never touching either axis.
Matching an equation to its graph
Telling linear, quadratic, cubic and reciprocal graphs apart by shape alone.
Exponential graphs
The shape of y = kˣ, growing or decaying, always crossing the y-axis at 1.
The sine and cosine graphs
The two waves between −1 and 1, repeating every 360°, separated by a shift.
The tangent graph
The repeating branches of y = tan x, with vertical asymptotes every 180°.
