- When Limiting Values Occur Suppose S(t) represents the average speed, in miles per hour, for a 100-mile trip that requires t hours. Explain why we expect S to have a limiting value.arrow_forwardWrite the formula for the function that we get when we stretch the identity toolkit function by a factor of 3, and then shift it down by 2 units.arrow_forwardLet N=f(H) give the number of days it takes a certain kind of insect to develop as a function of the temperature H (in C∘). At 35∘C—the maximum it can tolerate—the insect requires 10 full days to develop. An additional day is required for every 2∘C drop, and it cannot develop in temperatures below 5∘C. The domain is? The range is?arrow_forward
- An icicle that is 12 mm long melts at a constant rate of 1.2 mm per minute. Let t represent the number of minutes since the icicle started melthing and suppose R is a function such that R(t) represents the remaining length of the icicle (in mm) t minutes after it started melting. A.Write a function formula for R in terms of t. b.What is the domain of R relative to this context? Enter your answer as an interval. c.What is the range of R relative to this context? Enter your answer as an interval. d.What is the domain of R−1 relative to this context? Enter your answer as an interval. e.What is the range of R−1 relative to this context? Enter your answer as an interval. f.Solve R(t)=6.6 for t. t= g.What does your solution in part (f) represent in this context? Select all that apply. How long it takes for the icicle to melt completely. How many minutes since the icicle started melting when it is 6.6 mm long. The length of the icicle (in mm) 6.6 minutes after it started…arrow_forwardGiven the function (photo below), which statement is true about h(x)? The function is decreasing on the interval (–3, ∞). The function is decreasing on the interval (–∞, –1). The function is increasing on the interval (–∞, –3). The function is increasing on the interval (–1, ∞).arrow_forwarda Graph the function b. For x < 0, what is ƒ′(x)?c. For x > 0, what is ƒ′(x)?d. Graph ƒ′ on its domain.e. Is ƒ differentiable at 0? Explainarrow_forward
- A rancher wants to use a fence as an enclosure for a rectangular cattle pen with area 1024 square feet. (a) Suppose he decides to make one side of the pen 64 feet long. Draw a picture of the pen.1. What would be the total amount of fence needed if the pen were a square? ft2. Find a formula for a function F = F(L) that gives total amount of fence, in feet, required in terms of the length L, in feet, of one of its sides. (Hint: First draw a picture of the pen and label one side L. Next figure out the lengths of the other sides in terms of L.)F =arrow_forwardEvaluate the price wise function at the given value of the indépendant variable. Evaluate at f(4). f(x)=6x-1 if x<0 7x+3 if x was greater than or equal to 0arrow_forwardA step function assumes a constant value between consecutive integers n and n 1. Make a plot of the step function f +x/ whose value is n2 when n x n 1. Use the domain 0 x 20.arrow_forward
- 2. Find the value for the function; Find f(x+1) when f(x) = x^2 - 6/ x - 3arrow_forwardThe table gives the approximate monthly average temperatures in degrees Fahrenheit in a certain city. In this table x represents the month with x= 0 corresponding to July. If the numbers in the table correspond to an even function f with domain{?| −6 ≤ ? ≤ 6} what is the average temperature in March?arrow_forwardFind the absolute maximum and minimum values of the following function on the given into then grab the function identify the points on the graph where the absolute extreme occurarrow_forward
