Question
From the curve y = x, draw y = x + 1
Solution
| x | 0 | 1 | 2 | 3 | − 1 | − 2 | − 3 |
| y | 0 | 1 | 2 | 3 | − 1 | − 2 | − 3 |
y = x + 1
| x | 0 | 1 | 2 | 3 | − 1 | − 2 | − 3 | − 4 |
| y | 1 | 2 | 3 | 4 | 0 | − 1 | − 2 | − 3 |
The graph of y = x + 1 causes the graph y = x shift to upward by 1 unit.
The graph of y = f(x) + d, d > 0 causes the graph y = f(x) a shift to the upward by d units.
