plsHelp

Find the intervals which proves that function is upward/increase. a) f(x)=1-x2 b) f(x)=x2-2x

Solve the indifinite integral: f(5x+3)7 dx

-A sample consist 90% NaOH and 10% CaO,whats the concentration of NaOH in the solution of this 3g sample,dissolved in 250cm3. -How many cm3 of H2SO4 with concentration of 0.255M are needed for titration of 100cm3 of this solution

Steve thanks very much, may i have your email id so i can ask a question with integrals/limits which i cant write here
