HalloDiana, kakak akan bantu jawab ya :) Jawaban: 3 Ingat bahwa! f (x)=ax^n maka turunannya f' (x)=nax^ (n-1) syarat stasioner f' (x)=0 Untuk menentukan nilai fungsi f (x), substitusikan nilai x=c ke dalam fungsi f (x) sehingga diperoleh nilai f (c). Dari soal diketahui y=x³−3x+1 maka titik stasionernya y'=0 3x²-3=0 3x²=3 x²=1 x=±√1 b). Mencari titik potong dengan sumbu-y. y = f(0) y = (0)² + 7(0) + 6. y = 6 . Titik potong pada sumbu-y adalah (c). Mencari sumbu simetri. Dari fungsi kuadrat, a = 1, b = 7, dan c = 6. Substitusikan koefisien a dan b ke dalam rumus. Diperoleh sumbu simetri [Soal-b] f(x) = x² + 2x - 3 (a). Mencari titik potong dengan sumbu-x. x² + 2x - 3 Freemath problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. 周边交通366路 (宋家庄→黄村火车站)；474路 周边商业：斑斓商业配套，礼赞品质生活；西红门板块依 周边公园：得天独厚自然生态，区域难得宜居胜境；占位 周边医院：近享尖端化医疗，为健康保驾护航；西红门医 周边学校：项目周边约2km以内范围 Login- University of Phoenix Loading Theprojection of the line x + 1 − 1 = y 2 = z − 1 3 on the plane x – 2y + z = 6 is the line of intersection of this plane with the plane A 2x + y + 2 = 0 .
