QuestionIf f(x)=x210xf(x)=x^{2}-10 x \begin{tabular}{|c|c|c|} \hline yy-intercept & Choose... & - \\ \hline The graph is & Choose. & - \\ \hline Discriminant Δ\Delta & Choose... & - \\ \hline Head Vertex is & Choose... & - \\ \hline x-intercept & Choose... & * \\ \hline \end{tabular}

Studdy Solution
لحساب x x -الاعتراض، نحل المعادلة f(x)=0 f(x) = 0 .
x210x=0 x^2 - 10x = 0
نستطيع تحليلها إلى:
x(x10)=0 x(x - 10) = 0
وبالتالي، الحلول هي x=0 x = 0 و x=10 x = 10 .
النقاط الرئيسية هي: - y y -الاعتراض: 0 0 - الرسم البياني هو قطع مكافئ مفتوح لأعلى. - المميز Δ\Delta: 100 100 - رأس القطع المكافئ: x=5 x = 5 - x x -الاعتراض: 0 0 و 10 10
