the value of ` lim_(h to 0) (f(x+h)+f(x-h))/h` is equal to

Let f(x)=2x^(1//3)+3x^(1//2)+1. The value of lim_(hrarr0)(f(1+h)-f(1-h))/(h^(2)+2h) is equal to

If f'(2)=1 , then lim_(h to 0)(f(2+h)-f(2-h))/(2h) is equal to

If f (x) is differentiable at x = h , find the value of lim_(s to h)((x+h)f(x)-2hf(h))/(x-h)

If f(x) is derivable at x=3 and f'(3)=2 , then value of lim_(hto0)(f(3+h^(2))-f(3-h^(2)))/(2h^(2)) is less than

let f(x) be differentiable at x=h then lim_(x rarr h)((x+h)f(x)-2hf(h))/(x-h) is equal to

f(x)=3x^(10)7x^(8)+5x^(6)-21x^(3)+3x^(2)7, then is the value of lim_(h rarr0)(f(1-h)-f(1))/(h^(3)+3h) is

Let f(x)=3x^10-7x^8+5x^6-21x^3+3x^2-7 , then the value of lim_(h->0) (f(1-h)-f(1))/(h^3+3h)
