MULTIPLE CHOICE Red Oak Tree Diameter vs. Age Diameter (in.), x 1.27 2.48 3.08 4.47 5.07 6.24 Age (years), f(x) 5 A 10 The function that could represent the table above, where .x represents the diameter in inches and f(x) rep- resents the age in years. What does the notation (4.47) = 18 represent in terms of the red oak tree? B 12 18 20 с When the diameter of the red oak tree is 4.47 inches, the tree is 18 years old. When the diameter of the red oak tree is 18 inches, the tree is 4.47 years old. 25 18 times the diameter of the red oak tree gives the age of the tree (4.47 years old).

What is the domain and range of y=5(3)^x This equation is a function Pls do not write infinity sign please use greater or less than sign with numbers and variables if needed

x + 6 Suppose f(x) x2 - 4 a. Notice that f(5) = 0.5238. What does this tell us about the numerator and the denominator of f? When x = 5, the value of is times as large as the value of x? 4. (Hint: In this case, the first answer should be an expression in terms of x, and the second answer should be a number.) b. Use function notation to represent the answer to the question, "when x = 11.2, x + 6 is how many times as large as x? – 4?". Preview Submit

U.S. Population The U.S. population can be modeledfor the years 1960–2060 by the function p = 2.6x +177, where p is in millions of people and x is in yearsfrom 1960. During what year does the model estimatethe population to be 320,000,000?(Source: www.census.gov/statab)

A spherical balloon is being inflated with air. The radius R, in inches, of the balloon is a function of the volume V, in cubic inches, of air in the balloon. The formula is shown below. R = (34) ¹/3 The volume V is a function of time t, in seconds, and the formula is shown below. V = 1.8 +0.9t (a) Use function composition to find a formula for R as a function of t. R = (b) What is the radius at time t = 6 seconds? (Round your answer to two decimal places.) in
