Explanation Given: The function is f ( x ) = | x | + 1 . a. y = f ( x − 1 ) b. y = − f ( x ) c. y = − f ( x ) + 2 d. y = f ( x − 1 ) − 2 e. y = f ( x + 1 ) Calculation: Part a: Find the points to draw the graph of the function y = f ( x − 1 ) . The given function is f ( x ) = | x | + 1 . Substitute x − 1 in place of x . f ( x − 1 ) = | x − 1 | + 1 We can rewrite it as: y = | x − 1 | + 1 Put x = − 2 in the given function. y = | ( − 2 ) − 1 | + 1 = 3 + 1 = 4 Put x = − 1 in the given function. y = | ( − 1 ) − 1 | + 1 = 2 + 1 = 3 Put x = 0 in the given function. y = | 0 − 1 | + 1 = 1 + 1 = 2 Put x = 1 in the given function. y = | 1 − 1 | + 1 = 0 + 1 = 1 Put x = 2 in the given function. y = | 2 − 1 | + 1 = 1 + 1 = 2 The points are: x − 2 − 1 0 1 2 y 4 3 2 1 2 The graph is: Hence, the graph of option (a) is (v). Part b: Find the points to draw the graph of the function y = − f ( x ) . The given function is f ( x ) = | x | + 1 . Multiply with ( − ) of the above function. − f ( x ) = − ( | x | + 1 ) We can rewrite it as: y = − ( | x | + 1 ) Put x = − 2 in the given function. y = − ( | − 2 | + 1 ) = − ( 3 ) = − 3 Put x = − 1 in the given function. y = − ( | − 1 | + 1 ) = − ( 2 ) = − 2 Put x = 0 in the given function. y = − ( | 0 | + 1 ) = − ( 1 ) = − 1 Put x = 1 in the given function. y = − ( | 1 | + 1 ) = − ( 2 ) = − 2 Put x = 2 in the given function. y = − ( | 2 | + 1 ) = − ( 3 ) = − 3 The points are: x − 2 − 1 0 1 2 y − 3 − 2 − 1 − 2 − 3 The graph is: Hence, the graph of option (b) is (iv). Part c: Find the points to draw the graph of the function y = − f ( x ) + 2 . The given function is f ( x ) = | x | + 1 . Multiply with ( − ) of the above function. − f ( x ) = − ( | x | + 1 ) Add 2 on both sides. − f ( x ) + 2 = − | x | − 1 + 2 = − | x | + 1 We can rewrite it as: y = − | x | + 1 Put x = − 2 in the given function. y = − | x | + 1 = − | − 2 | + 1 = − 1 Put x = − 1 in the given function

Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:
