A function `phi(x)` is called a primitive of `f(x)`; if `phi'(x) = f(x)`

If d/(dx)(phi(x))=f(x) , then

If the function f(x) increases in the interval (a,b), and phi(x)[f(x)]^(2), then phi(x) increases in (a,b)phi(x) decreases in (a,b) we cannot say that phi(x) increases or decreases in (a,b). none of these

If two real functions f(x) and phi(x) are defined respectively by f(x)= sqrt(x-2) and phi(x)=x+3 , then find each of the following functions : f+phi

If two real functions f(x) and phi(x) are defined respectively by f(x)= sqrt(x-2) and phi(x)=x+3 , then find each of the following functions : (f)/(phi)

If two real functions f(x) and phi(x) are defined respectively by f(x)= sqrt(x-2) and phi(x)=x+3 , then find each of the following functions : (1)/(phi)

If two real functions f(x) and phi(x) are defined respectively by f(x)= sqrt(x-2) and phi(x)=x+3 , then find each of the following functions : (1)/(f)

If two real functions f(x) and phi(x) are defined respectively by f(x)= sqrt(x-2) and phi(x)=x+3 , then find each of the following functions : fphi

If a function f(x) increases in the interval (a,b). then the function phi(x)=[f(x)]^(n) increases in the same interval and phi(x)!=f(x) if
