Practice problem
Write the following set SSS in roster form. (Here Z\mathbb{Z}Z is the set of integers.) S={x2∣x∈Z,−1≤x≤2 or 6<x≤10}S = \{x^2 \mid x \in \mathbb{Z} , -1 \leq x \leq 2 \text{ or } 6<x\leq{10} \}S={x2∣x∈Z,−1≤x≤2 or 6<x≤10}
{0,1,4,9,16,25,36,49,64,81,100}\{0,1,4,9,16,25,36,49,64,81,100\}{0,1,4,9,16,25,36,49,64,81,100}
{0,1,4,49,64,81,100}\{0,1,4,49,64,81,100\}{0,1,4,49,64,81,100}
∅\emptyset∅ (empty set)
{0,1,4,36,49,64,81,100}\{0,1,4,36,49,64,81,100\}{0,1,4,36,49,64,81,100}
Type a concept, like “slope” or “photosynthesis”.
