For the function f(x) = x + x +4, find and simplify the difference quotient: {f(x+h)-f(x)/(h)} For the function f (T) = $2 + +

For the function f(x) = x² + x +4, find and simplify the difference quotient: {f(x+h)-f(x)/(h)}

For the function f (T) = $2 + + 4, find and simplify the difference quotient: f(x+h) f(x)
