Question

Which of the following is an approximate solution for f(x) = g(x)?


(a) x = −2
(b) x = 0
(c) x = −1
(d) x = 1

Answer 1

C. Because an intersection between f(x) and g(x) is at approximately -1

Answer 2

Answer:

(c) x = −1

Explanation:

The graph has two functions, which are f(x) and g(x) and a graph. In the graph, we can follow their intersections. Those would be the parts of the line that would make the functions to have the same value. The first intersection is really close to -1, se second is very unclear, most likely beyond 1. Since the highest number is 1 and the intersection is very close to -1, we have to go with the approximate answer.
