Question

Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit. Select all that apply. f(x)=2(3)^x g(x)=10log(x+3)

Answer 1

Answer:

The correct option is 1.

Step-by-step explanation:

The system of equations is

$f(x)=2(3)^x$

$g(x)=10\log (x+3)$

Using graphing tool we can draw the graph as shown below.

From the below graph it is clear the graph of f(x) and g(x) intersect at (-1.944,0.236) and (1.004,6.025).

$(-1.944,0.236)\approx (-2,0.2)$

$(1.004,6.025)\approx (1,6)$

The approximate solutions of the given system of equations are (-2,02) and (1,6). Therefore only option 1 is correct.
