FUNCTION NOTATION WORD PROBLEMS. Problem 1 : The value in dollars, v(x), of a certain car after x years is represented by the equation v(x) = 25,000(0.86) x. To the nearest dollar, how much more is the car worth after 2 years than after 3 years? 1) 2589 3) 15,901. 2) 6510 4) 18,490. Solution: v(x) = 25,000(0.86) x. After 2 years: x = 2

Which function can be used to find the height of the car above the barge after s seconds. Let h = height. 6. A Mars rover traveled 1 mile in 15 minutes. The rover travels at a constant speed. Which function can be used to find d, the total distance traveled in x hours? 7. Two web page developers offer different plans for their services.

Interpreting Function Notation Word Problems 1. Charlie worked for a stone setting company this past summer. He earned $50 just for coming to work and an additional $30 every hour for each hour he worked. The linear function E(t) = 50 + 30t represents Charlie’s earnings E as a function of time worked t (in hours). 1.a. Explain what E(4 ...

Form A uses y, while Form B uses f (x). This f (x) notation is called function notation and can be used with functions as a substitute for y. 1. Suppose that f (x) = 7x – 3 . a. Find f(3) b. Find f(-5) 2. Suppose h (x) = -2x + 10 . a. Find h(-8) b. Find h(5) 3. Suppose that f (x) = 4 x + 1 . …

Functions Word Problem. by Pujan (Ny, usa) The value of a 1996 Mustang, in thousands of dollars, is a function of the age a of the car, in years. Let V=f(a) be the function that represents the value of the car when it is a years old. Assume V is a linear function. (a) Interpret the equation f(3)=27 in practical terms.

Example 1 : The formula for finding the circumference C of a circle with radius r is C = 2∏r. Find : a) The circumference of a circle of radius 4.2 cm. b) The radius of a circle with circumference 112 cm. c) The diameter of a circle with circumference 400 meters. Solution : (a) Radius (r) = 4.2 cm. Circumference of a circle C = 2∏r.
