1. y=10
2. (1,3)
3. I'm not sure.
4. KX=14 m
There is a solution for f(x) = g(x) between x = 1 and x = 2.
0.1[x+250]=5000
10(0.1[x+250]=5000
1[x+250]=50,000
x+250=50,000
-250 -250
x = 49,750
The first number in the couplet is the distance along the x-axis (i.e. distance from the y-axis). We can read 0.8 from the graph.
The second number is the distance along the y-axis (i.e.distance from the x-axis). We can read 6.7 from the graph.
So approximately, we have the point as (0.8, 6.7).
Round the numbers to the nearest integer and you'll get the required answer choice.
