Math Problem Statement

Determine o domínio das seguintes funções: (a) f(x) = 1 x2−4 Resp: {x ∈ R/x ̸= −2 ou x ̸= 2} (b) f(x) = √ x 2 − 4 Resp: {x ∈ R/x ⩽ −2 ou x ⩾ 2} (c) f(x) = √ 1 x2−4 Resp: {x ∈ R/x < −2 ou x > 2} (d) f(x) = 1 1+√ x Resp: R+ (e) f(x) = √ x x2−9 Resp: R+ − {3} (f) f(x) = √ x 2 − 3x − 4 (g) f(x) = 1 √3 2x+3 (h) f(x) =√ x 2 − 4 + √ x 2 − x − 6
