Question

Answer 1

1: \(=\dfrac{5}{9}\left(\dfrac{13}{17}-\dfrac{-4}{17}\right)=\dfrac{5}{9}\)

2: f(0)=1/4

f(1/2)=1/4-1=-3/4

Answer 2

1 \(\dfrac{5}{9}\)

2 f(0) = \(\dfrac{1}{4}\)

   f(\(\dfrac{1}{2}\)) = \(\dfrac{-3}{4}\)

Answer 3

1,\(\dfrac{5}{9}\)

2, f(0)=\(\dfrac{1}{4}\),f(\(\dfrac{1}{2}\))=\(\dfrac{-3}{4}\)
