The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis. So if you plug in y=0 into the equation you can solve for the x coordinate.
4x-2(0)-8=0
4x-8=0
4x=8
x=2
So the x-intercept is the point (2,0)

Answer:
Step-by-step explanation:
In this problem, the initial area of the forest at time t = 0 is
After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.
So for instance, after 1 year, the area is
After 2 years,
And so on. So, after t years, the area of the forest will be
And by substituting the value of A0, we can find an explicit expression:
