1.If the function f(x)={aπ−x+1,x≤5b∣x−π∣+3,x>5f(x) = \begin{cases} a\pi - x + 1, & x \le 5 \\ b|x - \pi| + 3, & x > 5 \end{cases}f(x)={aπ−x+1,b∣x−π∣+3,x≤5x>5 is continuous at x=5x = 5x=5, then the value of a−ba - ba−b is:a.52\frac{5}{2}25b.−72π−5\frac{-7}{2\pi - 5}2π−5−7c.72π−5\frac{7}{2\pi - 5}2π−57d.72π+5\frac{7}{2\pi + 5}2π+57Login to continueOnly logged in users canattempt or see the solution.
