Question
For the curve y = `x^((1/3))` given in Figure 1.68, draw
y = `(x + 1)^((1/3))`
Solution
y = `(x + 1)^((1/3))`
y3 = x + 1
When y = 0 ⇒ 03 = x + 1 ⇒ x = – 1
y = 1 ⇒ 13 = x + 1 ⇒ x = 0
y = 2 ⇒ 23 = x + 1 ⇒ x = 8 – 1 = 7
y = 3 ⇒ 33 = x + 1 ⇒ x = 27 – 1 = 26
y = – 1 ⇒ (– 1)3 = x + 1 ⇒ x = – 1 – 1 = – 2
y = – 2 ⇒ (– 2)3 = x + 1 ⇒ x = – 8 – 1 = – 9
| x | – 1 | 0 | 7 | 26 | – 2 | – 9 |
| y | 0 | 1 | 2 | 3 | – 1 | – 2 |
The graph of y = (x + 1)3 causes the graph y = `x^((1/3))` a shift to the left by 1 unit.
The graph of y = f(x + c), c > 0 causes the graph y = f(x) a shift to the left by c units.
