Graph the function y = cos(2x) on the interval [0, 2π].

The function y = cos(2x) has no graph on the interval [0, 2π]

The graph of y = cos(2x) on the interval [0, 2π] is a parabola

Graph of y = cos(2x) on the interval [0, 2π] is a straight line

Graph of y = cos(2x) on the interval [0, 2π] is a wave that starts at 1, dips to -1, rises back to 1, and repeats every π units.

Graph the function y = tan(x) on the interval [-π/2, π/2].

Graphing the function y = sin(x) instead

Plotting points at x = -π, -π/3, π/3, and π

Drawing horizontal asymptotes at y = ±π/2

Graphing the function y = tan(x) on the interval [-π/2, π/2] involves plotting points at x = -π/2, -π/4, 0, π/4, and π/2, and drawing vertical asymptotes at x = ±π/2.
