Answer:
x= -15
Step-by-step explanation:
Divide to both sides by -5 to isolate the variable.
<u>-5x</u>=<u>75</u>
-5 -5
x= -15
This gives you the answer of x= -15.
<h3>Answers:</h3>
- (a) The function is increasing on the interval (0, infinity)
- (b) The function is decreasing on the interval (-infinity, 0)
=======================================================
Explanation:
You should find that the derivative is entirely negative whenever x < 0. This suggests that the function f(x) is decreasing on this interval. So that takes care of part (b).
The interval x < 0 is the same as -infinity < x < 0 which then translates to the interval notation (-infinity, 0)
Similarly, you should find that the derivative is positive when x > 0. So the function is increasing on the interval (0, infinity)
