Answer:
x = 4
Step-by-step explanation:
8x - 9 = 6x - 1
Bring variables to the left side, whereas numbers to the right.
8x - 6x = - 1 + 9
2x = 8
x = 8 / 2
x = 4
The interval that f(x) is increasing is the distance from 200 to 300.
The minimum value of f(x) in the interval 0<x<300 is 200.
At a value of 500, the value of f(x) is 0.
The function can't be a quadratic function since there are two points in the graph where f(x) changes its rate from increasing to decreasing or the opposite. A quadratic function has only one of that point.
