hi guys my calculus test is coming up and i just wanna know if im doing these right, the information is blacked out but it asks questions so could anyone give me steps or tips or show me how to do it (along the lines since there are no real numbers to work out)

Question 1 Given? and? .

1. What is the equation of the tangent line .
2. What is the equation of the normal line .

Question 2 (10 points) Given the piecewise function

Use the definition of the derivative to determine if

f is differentiable at? . Show your work.

Question 3 (5 points) The graphs of f,g, and h

are given below.

?

Identify which function is the derivative of the other.

Question 4 (30 points) Use the rules of differentiation to compute the derivative of the following functions.Do not simplify your answer. It is not necessary to state the properties used.

Question 5 (10 points) The height ( ? ) of an object at t

is given by? . Suppose? and? . What is ? ?Use proper units for your answer.

Question 6 (10 points) For each step in the calculation below, fill in the missing pieces and state the property or properties that is or are used.

1. f1(x)=
2. f2(x)=
3. f3(x)=
4. f4(x)=
