<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)
Answer:
8x-5/4
Step-by-step explanation:
Cancel 5y x 5y/10 x 6y²=5/12y
8x-3y 5/12y
apply fraction rule a× b/c = a×b
____
c
8x-3y⁵/12y
8x-3y×5/12y
8x-3×5/12y
8x-3×5/12
=8x-5/4
The picture shows that the line is curved which means that it is non-linear, if it was linear the line would be straight.
