( b ) Use your table to complete the graph of y = 3^x for -2 ≤ x ≤ 2 .


[ 2 ]

( c ) Use the graph to find the solution of the equation.

3^x = 6

1 answer

From the graph, we can see that 3^x is between 5.2 and 9 when x is between 1.5 and 2. Therefore, the solution to the equation 3^x = 6 is x ≈ 1.7007.
