Answer:
Option D. 1 to 2.5
Step-by-step explanation:
<u><em>The complete question is</em></u>
Consider the graph of the quadratic function. Which interval on the x-axis has a negative rate of change?
Options:
A. –2 to –1
B. –1.5 to 0
C. 0 to 1
D. 1 to 2.5
see the attached figure to better understand the problem
we know that
The quadratic function in the graph represent a parabola open downward
The vertex represent a maximum
The x-coordinate of the vertex is approximately 0.5
The axis of symmetry is x=0.5
The function is increasing for x < 0.5 interval (-∞,0.5)
The function is decreasing for x > 0.5 interval (0.5,∞)
Remember that
If the function is decreasing, the rate of change is negative
If the function is increasing, the rate of change is positive
so
The rate of change is negative in the interval (0.5,∞)
therefore
Option A. –2 to –1 ----> rate of change is positive
Option B. –1.5 to 0 ----> rate of change is positive
Option C. 0 to 1 ---> (0,0.5) the rate of change is positive and (0.5,1) the rate of change is negative
Option D. 1 to 2.5 ---> <em>the rate of change is negative</em>
Answer:
(Part A) I know the mean of x will be 1.35
Step-by-step explanation:
Just do 9 percent of 15, I nessecarly dont know how to do that math but I looked it up and gave me 1.35. and you got the mean. here is the homework my teacher gave me : I hope this helps
