Answer:
Step-by-step explanation:
is formed by and , so we can begin by finding their slopes.
This means that:
As is acute, this means
Yes it’s possible to compose two functions. For an example f and g produces a function h such that h(x) = g(f(x)
Answer:
The function is increasing when the slope is greater than zero and decreasing when the slope is less than zero. Slope is (y2-y1)/(x2-x1) or the change in y divided by the change in x.
In this case the function is decreasing when x=[-8,-5) and when x=[4,8)
So in interval notation: x=[-8,-5)U[4,8)
