OBLICZ POLE ff: Oblicz pole figury ograniczone krzywymi y = x² , y = x²+2 y = 4 x≤0

Janek191: y = x² y = x² + 2 y = 4 x ≤ 0

Janek191: y = x² y = 4 −−−−−−−− x² = 4 ⇒ x = − 2 , bo x ≤ 0 oraz y = x² + 2 y = 4 −−−−−− x² + 2 = 4 x² = 2 ⇒ x = − √2 , bo x ≤ 0 −√2 0 0 P = ∫ 4 dx + ∫ ( x² + 2) dx − ∫ x² dx = −2 −√2 − 2
