Question: Suppose that f is a function given as f ( x ) = - x 2 - 4 x + 3 . Simplify the expression

Suppose that f is a function given as f(x)=-x2-4x+3.
Simplify the expression f(x+h).
f(x+h)= x2+h22xh4x+4h+3Incorrect
Simplify the difference quotient, f(x+h)-f(x)h.
f(x+h)-f(x)h =
The derivative of the function at x is the limit of the difference quotient as h approaches zero.
f(x)=limh0 f(x+h)-f(x)h =
