1. Direction: Write TRUE if the statement is true on the space provided before each number. Otherwise, write False for false statements. Justify your answer why the statement is false. Write your explanation after each statement. 1. In the function, the dependent variable is the output and the independent variable is the input. 2. Functions can be modeled by the "input-process-output" machine. 3. All relations are functions 4. All equations are functions. 5. All functions are equations. Il. Find the specified value. A. Given the function p(x) = 4x - 5 . find the answer of the missing table A B. Given the graph of the function, find the specified value (value of y) y = x? - 2x - 3 P(x) X 3 1. f(-1) 2. f(0) 2. -2 3. f(3) 3 . 4. 1(-2) -9 5. 1(4) 5. 0 Ill. Analyze and answer the problem 1. A certain chocolate bar costs P35,00 per piece. However, if you buy more than 10 pieces, they will be marked down to a price of P32.00 per piece. Use a piecewise function to represent the cost in terms of the number of chocolate bars bought. IV. Consider the following functions. f(x) = 5x - 2 P(x) = x -2 g(x) = x -4 (x) 5x Find 1 .
