Web3) Prove that the function f: R →R defined by f(x) = (x2 if x∈Q, 0 if x∈R\Q, is differentiable at 0, and computef′(0). Solution. Given x̸= 0, consider the difference quotient f(x) −f(0) x−0 = f(x) x. If x∈Q then we have f(x) x = 0, while if x∈R\Q then we have f(x) x = x. Thus in both cases we have f(x) x ⩽ x , and since lim Web11 apr. 2024 · Solution For Example 10: Let f:(0,∞)→[9,∞) defined as f(x)=x12+x24 +x4 . Check whether f is onto or not. Solution : f:(0,∞)→[9,∞) f(x)=x12+x24 +x4 Applying A.M., G.M. inequality 9x12+x21 +x21 +x21 +x talesshop co. ltd
If f:R→R is defined as f(x)=x2−2x−3 then f is (a) one-one but n.

(Hint: For y ∈ Range f, y = f (x) = 𝑥/ (𝑥 + 2) , … WebIf f: R → R, g: R → R are given by f (x) = (x + 1) 2 and g (x) = x 2 + 1, then write the value of f ∘ g (− 3). WebCurrently, we reported the synthesis of six novel salicylaldehyde-based thiosemicarbazones (BHCT1–HBCT6) via condensation of salicylaldehyde with respective thiosemicarbazide. Through various spectroscopic methods, UV–visible and NMR, the chemical structures of BHCT1–HBCT6 compounds were determined. Along with synthesis, a computational … two by two ulverston
