Question

The table shows values for functions f(x) and g(x) .

x f(x)=2^x−1 g(x)=1/2x
−2 −3/4 −1
−1 −1/2 −1/2
0 0 0
1 1 1/2
2 3 1
What is the solution to f(x)=g(x) ?

Select each correct answer.




x = −2

x = −1

x = 0

x = 1

x = 2

Answer 1

x = -1

x = 0

Explanation:

The solution to f(x) = g(x) is the value of x on the rows of the table where the value of f(x) is the same as the value of g(x). If we read your table correctly, you have ...

f(-1) = -1/2 = g(-1)

and

f(0) = 0 = g(0)

That is, f(x) = g(x) for ...

x = -1

x = 0
