B. Sketch each function below without using a graphing calculator. ***Construct a table of values with at least three (3) values of x for each piece of the function. Solve for y. Then, evaluate the following. Show your complete solution 3x +4, f(x) = }x² – 5, 5, x< -2 x2 5 f(x) = }-2x, - 25x<5 (2 –x², x< -2 7. 8. - 2sxs2 x>2 evaluate: evaluate: ƒ(-2)= f(-1,5) = f(6.5) = ƒ (5)= Page 1 of 1

Mia bought a used car for $9,500. It is expected that the value of the car will decrease by an average of $750 each year. Which function can be used to find the value of the car in x years after Mia purchased it? O f(x) = - 9500(x- 750) O f(x) = - 750(x +9500) O f(x) = 9500 + 750x O f(x) = 9500 - 750x 1 2 3 4 6 8 9. 10 Of

Suppose you take a straight piece of wire measuring 20 cm and cut it to make two pieces. You then take one piece and make it into a square, and the other piece and make it into a circle, like in the following picture: 20 cm- 20-x Write a function, 4(-x), that gives the total area of the circle and the square you A(x) а. make in this scenario. b. What is the domain of 4(.x)?

RyAnne has 8 coins and decided to begin a collection.    On the first day of collecting, she has 32 total coins in her collection    On the second day of collecting, she has 128 total coins in her collection   On the third day of collecting, she has 512 total coins in her collection Write a function that represents the number of coins as a function of the number of days, x.
