What is the significance of the limits provided in the midterm question?
They indicate the behavior of the function as it approaches certain values.

What does lim (x → 6) f(x) indicate?
It indicates the behavior of the function f(x) as x approaches 6.
What is the condition for δ in relation to x for the function f(x) = x/(x - 1)?
If δ < |x - 1|, then |f(x) - 2| < 0.1.

You MUST show your work.
How do you apply the definition of the derivative to f(x) = 4x + 3?
Calculate f(x + h) = 4(x + h) + 3 and then use the limit definition.
What is the limit of (1 - x)/(x - 1) as x approaches 1?

What does the Intermediate Value Theorem (IVT) help to prove?
It helps to prove that a function has a root within a certain interval.
What is the limit of (5x^2 - 7)/(2x - 5) as x approaches 0?

What is the formula to find the derivative of a composite function f(x) = g(h(x))?
Use the chain rule: f'(x) = g'(h(x)) * h'(x).
What does it mean for a function to be not differentiable at a point?
It means that the function does not have a defined derivative at that point.
What can be said about the function based on the graph?
There are 2 values for which the function is not differentiable; the function is continuous from the left at x = 0.
What does the Squeeze Theorem help to determine?
It helps to find the limit of a function by 'squeezing' it between two other functions.
What are the horizontal asymptotes of the function f(x) = (4x^3 - 10x + 7)/(3x^2 + x - 3)?
y = 4/3.
What does the Intermediate Value Theorem guarantee for a continuous function on the interval [1, 5]?
There exists at least one c in [1, 5] such that f(c) = 2.
How can you determine the number of discontinuities in a function f?
By analyzing the limits and the defined points of the function.
What is the definition of the derivative using First Principles?
f'(x) = lim (h -> 0) [(f(x + h) - f(x)) / h].
