Q12·Section A (Section A)·12 of 60Number of intersections of two curvesLet f,g:R→Rf,g:\mathbb R\to\mathbb Rf,g:R→R be defined by f(x)=x2−cosx2f(x)=x^2-\dfrac{\cos x}{2}f(x)=x2−2cosx and g(x)=xsinx2g(x)=\dfrac{x\sin x}{2}g(x)=2xsinx. Then OptionsAf(x)=g(x)f(x)=g(x)f(x)=g(x) for more than two values of xxxBf(x)≠g(x)f(x)\ne g(x)f(x)=g(x), for all xxx in R\mathbb RRCf(x)=g(x)f(x)=g(x)f(x)=g(x) for exactly one value of xxxDf(x)=g(x)f(x)=g(x)f(x)=g(x) for exactly two values of xxxPick an option to check your answer.Show answerShow solution Report a problem with this question← Q11All questionsQ13 →Keyboard: A–D answer · S solution · ←/→ previous/next
