Question

Let f : R → R be a continuous and differentiable function such that f 2 = 6 and f ' 2 = 1 48 . If ∫ 6 f ( x ) 4 t 3 d t = x - 2 g x , then l i m x → 2 g x is equal to, 24, 18, 12, 36

MARKS App · Accepted Answer

l i m x → 2 g x = l i m x → 2 ∫ 6 f x 4 t 3 d t x - 2 0 0 form . By using L'Hospital rule = l i m x → 2 4 . f 3 ( x ) ⋅ f ' x 1 = 4 f 3 2 f ' 2 = 4 × 6 × 6 × 6 × 1 48 = 18 .
