Answer:
Explanation:
You just need to find the corresponding coordinates on the graph by using one of the coordinates and the graph.
4) Find f(0.8)
Find the point 0.8 on the x-axis and check the point the vertical line from that point crosses the graph. See what that point is on the y-axis.
This is point 1
The answer is 1, the point has coordinates (0.8, 1)
5) Find x when f(x) = 3
Find the point of the graph against 3 on the y- axis
And check what is corresponding point on x-axis, this is point 4
So the answer is 4, the point has coordinates of (4,3)
