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)
Answer:
43.15
Step-by-step explanation:
1/2( b ( times ) h ) is the formula
h^2 - 12h + 20 can be factored to:
(h-10)(h-2)
These cannot be zero so, h cannot be 10 or 2.
Yes the fractions are equivalent. 5/5 is another equivalent fraction
