(a) Graph $g (x) = 3^{x} - 9$ g
(b) Find the zero of g.
(c) Based on the graph, solve $g (x) < 0$

Short Answer

Expert verified

a) The graph of the function is

b) The zero of the function is $x = 2$

c) $g (x) < 0$ when $x < 2$

Step by step solution

Step !: Given information

We are given a function $g (x) = 3^{x} - 9$

We create a table

We get

x	$g (x) = 3^{x} - 9$
-1	$- \frac{28}{3}$
0	-8
1	-6
2	0
3	18

The graph of the function can be given as

Part b) Step 2: Solve for g(x)=0

We get,

$g (x) = 0 3^{x} - 9 = 0 3^{x} = 9 3^{x} = 3^{2} x = 2$

The zero of the function is at $x = 2$

Part c) Step 1: Solve for g(x)<0

As the zero of the function is at x=2

Hence $g (x) < 0$ when $x < 2$
