Calculus
yes I know that but I need to steps for how you find the derivative.

Calculus
thanks allie but i need someone to show the work to how they got those answers too please :)

Calculus
Let f(x)=x^2+5x-3. Find f′(x) and find f′(1).

Calculus
Take the derivative of the following functions. You do NOT need to simplify. h(x)=(6x^3+2x)/(x^2-3x+5)= F(x)=(5x^2+1)(3x-2) =

Calculus
Suppose that f(2)=3 and f′(2)=5. Let g(x)=x^3f(x). Evaluate g′(2). Your final answer should be a single number.

Calculus
Take the derivative of f(x) = 4x^3+(7/x^2).

Calculus
Let f(x)=21−x^2 The slope of the tangent line to the graph of f(x) at the point (−4,5) is ______ . The equation of the tangent line to the graph of f(x) at (−4,5) is y=mx+b for m=______ and b=_______.

Calculus
For what values of x is the tangent line of the graph of f(x)=8x3+36x2+46x−72 parallel to the line y=−2x+1.9 ? Enter the x values in order, smallest first, to 4 places of accuracy: x1= ≤ x2=

Calculus
If f(x)=(3x)/(1+x^2) find f′(4). Use this to find the equation of the tangent line to the curve y=3x1+x2 at the point (4,0.70588). The equation of this tangent line can be written in the form y=mx+b where m is: and where b is:

Calculus
If f(x)=(3)/(x^2) find f′(4).
