The function is decreasing on the interval (- infinity, + infinity).
812.30/83 = 9.78674698.....
Nearest tenth means one number under decimal place so...

Explanation: The 9.7... rounded up to 9.8 because the number after the tenths place (in this case the number after the 7) is greater or equal to 5.
Answer:
<u>The only x-intercept is x = 1</u>
Step-by-step explanation:
The equation is:

We can substitute y for r(x), to write in the notation:

To get y-intercept, we put x = 0
and
To get x-intercept, we put y =0
We want to find x-intercepts here, so we substitute 0 into y and solve for x. Shown below:

<u>The only x-intercept is x = 1</u>
