If `f(x)=2x^2-3x+5,` find f(a+h) and `(f(a+h)-f(a))/(h)`

If f(x)=|x|-2x , find f(-1),f(1) and f(-h).

f(x)=x^(3), find (f(x+h)-f(x))/(h)

If f(x)=x^2-5x+7, find f(2), f(-2), f(x+h), f(x^2+2) and (f(x+h)-f(x))/(h).

If f(x)= x^2 , then (f(x+h)-f(x))/(h) =

If f(x)=1/(4x^(2)) , then proved that (f(x-h)-f(x+h))/h=x/((x^(2)-h^(2))^(2))

(1) If f(x) = sqrt(x) , prove that : (f(x + h) - f(x))/(h) = (1)/(sqrt(x + h) + sqrtx) . (2) If f(x) = x^(2) , find : (f(1.1) - f(1))/(1.1 - 1) .

If f(x)=(1)/(x), evaluate lim_(h rarr0)(f(x+h)-f(x))/(h)

Given f(x) = 3x - 9 , find f(-1), f(3), f(x+h) and f(x^2-1).

If f(x)=x-1, g(x)=3x , and h(x)=5/x , then f^(-1)(g(h(5))) =
