Question

The graph below shows two functions:

Based on the graph, what are the approximate solutions to the equation −3x + 8 = (0.25)x?

1.9 and −2.6
8 and 2.6
1 and 2.6
−1.9 and 2.6

Answer 1

D) -1.9 and 2.6 are the solutions because when x=-1.9 and x=2.6 we have two points where the graph are cut. That is to say we have the same points in both graphs.

Explanation:

Answer 2

D) -1.9 and 2.6 are the solutions because when x=-1.9 and x=2.6 we have two points where the graph are cut. That is to say we have the same points in both graphs.

Explanation:

The approximate solution of the equations are: D) -1.9 and 2.6Step-by-step explanation: We have to find the approximate solution to the equation: i.e. the approximate solution are the x-value of the point of intersection of the graphs of the function: and Hence, the approximate solution from the graph is: D) -1.9 and 2.6
