Create an educational math diagram showing the limit problem with substitution f(x) → t. - Show x approaching 2 with an arrow labeled "x → 2" - Show f(x) approaching 0 with an arrow labeled "f(x) → 0" - Introduce t = f(x) with a label "t = f(x)" - Show f(f(x)) rewritten as f(t) with an arrow labeled "f(f(x)) = f(t)" - Show t approaching 0 with an arrow labeled "t → 0" - Include arrows connecting each step to visualize the flow - Style: clean, simple math textbook illustration - Fonts: small and clear - Colors: light background, dark text, minimal distractions - Make it easy to follow the sequence of substitution and limits Mehr sehen
