Respuesta :
The points which lie on the graph of f(x) = log9x are; (9, 1) and (81, 2)
Solution Points on a graph
The points which lie on the graph can be tested for as follows;
For (0, 1)
- f(0) = log₉(0)
- f(0) = log ₉ 0 = 0. ....Not true
For (3, 243)
- f(3) = log ₉ (3)
- f(3) = 1/2log₉9 = 1/2....Not true
For (9, 1)
- f(9) = log₉ (9)
- f(9) = 1 .....True
For (81, 2)
- f(81) = log₉ (81)
- f(81) = log ₉ (9)²
- f(81) = 2 log₉ (9)
- f(81) = 2....True
