Recall that we can describe some or all of the input-output pairs of a function by means of an equation, a graph, a table, or words. Let f(x) = 12(2)^. a. Describe five input-output pairs of f by using a table. b. Describe the input-output pairs of f by using a graph. c. Describe the input-output pairs of f by using words. a. Complete the table below. f(x) -2 ns 12:T Activate Windows Ga to Sertings to activate Wiodows 3/18 urces N10 12

A salesperson is paid a base salary of $2000 a month plus a 4% commission on their sales of x dollars. Write a linear function P(x) that represents the salesperson's total monthly pay, P (in dollars) in terms of their sales x. Then use that linear function to determine the value of x that will result in a monthly pay of $3120. Enter just the value of x that will result in a monthly pay of $3120 in the answer box. x=? dollars

The thickness of ice y in the Gladstone Glacier was 450 feet in 1990. By 2005, the thickness had shrunk to 400 feet. Let x be the elapsed number of years since 1990. Write a linear function that models this data. Then use the function to find the given value. (Simplify your answer and round to TWO decimal places, including zeros as needed. Example: 2 should be written as 2.00. Do not include commas.) Estimate the year when the Gladstone Glacier will be 350 feet thick. (Round your answer to TWO decimal places, including zeros as needed. Example: 2 should be written as 2.00. Do not include commas.)

Body surface area is an important piece of medical information because it is a factor in temperature regulation as well as some drug level determinations. The Mosteller formulat gives one way of estimating body surface area 8 in square meters. The formula uses the weight w in kilograms and the height h in centimeters. The relation is Vhw 60 In this exercise we consider people who are 190 centimeters tall. (a) Write a formula for 8 as a function of w. (b) Make a graph of 8 versus w. Include weights up to 100 kilograms. 3.0 3.0r 25 25 20 20 15 15 1.0 1.0 05 0.5 00 w 00 20 40 60 80 100 20 40 60 80 100 3.0. 3.0 25 25 20 20 1.5 15 1.0 1.0 05 05 w 100 0.0 20 10 60 80 20 10 60 80 100 (c) Is the graph you made in part (b) concave up or concave down? O concave up O concave down (d) In this part we consider the effect of weight gain on men who are 190 centimeters tall. Would the weight gain have a greater effect on surface area for a lighter man or for a he avier man? O lighter man O heavier man
