Answer - 31 : -
Answer - 32 : -
Answer - 33 : - ज्ञात है- f(x) = cos x²
f(c) = cos c²अत: f(x) = cos x² एक संतत फलन है। इति सिद्धम्
Answer - 34 : - ज्ञात है- f(x) = | cos x|माना x = c ∈ R पर,
f(c) = | cos c|अतः x = c ∈ R पर F एक संतत फलन है।। इति सिद्धम्
Answer - 35 : -
Answer - 36 : - ज्ञात है- f(x) = |x|-|x +1|f(x) = – x -[-(x + 1)] जबx< – 1]= -x + x + 1 = 1f(x) = – x – (x + 1), [जब –1≤ x < 0]= – x – x – 1= – 2x – 1f(x) = x – (x + 1), जब x≥0= x – x – 1 = -1
