For the curve y = x3 given in Figure 1.67, draw
y = x3 + 1 
Advertisements
Solution
y = x3 + 1
| x | 0 | 1 | – 1 | 2 | – 2 |
| y | 1 | 2 | 0 | 9 | – 7 |
The graph of y = x3 + 1, causes the graph y = x3 a shift to the 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.
