If f(x)=a/(3-x) where X doesn't equal to 3 and g(x)=11-bx^2, f^(5)=4/5 and fg(2)=1/2Find the values of a and b!

F(5)=4/5                                                                                                                                                a=-8/5

g(2)=11-4b then

put value of g(2)in last equation

then get value of b

 

with regards

these types of questions are simple practice
