Suppose f(x) is defined as shown below. a. Use the continuity checklist to show that f is not continuous at 2. b. Is f continuous from the left or right at 2? c. State the interval(s) of continuity. $\begin{aligned} f(x) = \begin{cases} x^2+3x & \text{if } x>2\\ 4x & \text{if } x \le 2 \end{cases} \end{aligned}$ a. Why is f not continuous at 2? A. $\lim_{x \to 2} f(x)$ does not exist. B. f(2) is not defined. C. Although $\lim_{x \to 2} f(x)$ exists, it does not equal f(2). b. Choose the correct answer below. A. f is continuous from the right at 2. B. f is not continuous from the left or the right at 2. C. f is continuous from the left at 2. c. What are the interval(s) of continuity? (Simplify your answer. Type your answer in interval notation. Use a comma to separate answers as needed)

Present value with periodic rates. Cooley Landscaping needs to borrow $25,000 for a new front-end dirt loader. The bank is willing to loan the money at 9.5% interest for the next 10 years with annual, semiannual, quarterly, or monthly payments. What are the different payments that Cooley Landscaping could choose for these different payment plans? What is Cooley's payment for the loan at 9.5% interest for the next 10 years with annual payments? $3981.65 (Round to the nearest cent.) What is Cooley's payment for the loan at 9.5% interest for the next 10 years with semiannual payments? $1963.76 (Round to the nearest cent.) What is Cooley's payment for the loan at 9.5% interest for the next 10 years with quarterly payments? $ (Round to the nearest cent.)
Fall 2021 1 Introductory calculus course. 1. Show that the function of x is a solution to the differential equation d^2y/dx^2 - a^2y = 0. 2. Note that v = -dy/dx, where dy/dx represents the derivative of y with respect to x. 3. Suppose Y(t) is dependent on a real-valued variable z. Starting with P = Pr(Y = 1) and the Gibbs form P = e^(-E/kT) for some energy E and partition function Z, show that it reduces to the logistic model P = 1/(1 + e^(-z)). 4. Find the range of b such that 0 < b < 1. Find a function for which b has a range of (-1,1) and then express it in terms of the hyperbolic tangent function. Suppose negative N is a random variable with a probability density function (pdf) in black, and positive P is a random variable with a pdf in green as illustrated in the figure. For fixed T in R, the True Positive Rate is defined as TPR(T) = Pr(P > T). What is TPR(T) in terms of p? 6. For fixed T in R, the False Positive Rate is defined as FPR(T) = Pr(N > T). What is FPR(T) in terms of nz?
