The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
5/6 divided by 3/4
First you do KCF (Keep. Change. Flip.)
Keeping the 5/6.
Changing the 3/4 to 4/3
And the new operation is multiplication as it’s the inverse of division.
So this is how it looks like:
5/6 • 4/3
Now, you can’t cross simplify since none of them can’t be reduced.
So the product of 5/6 and 4/3 is 20/18. And the mixed number is 1 2/8.
Simplifying the mixed number is 1 1/4.
I hope this helped.
I think she would have to divide 2/3 by 1/2. So you would do 2/3 x 2/1 and since 2/1 is equal to 2 the answer would be B

The slope is: -0.6
The Y-Intercept is: -3.4
Answer:
Option B. y = cosx + 1
Step-by-step explanation:
To understand the given graph we will note down it's features as below.
1). Since it's a periodic function and y value of graph is maximum at x=0 so its a cosine function.
2). Vertical shift of the graph is 1 means y=0 is the mid line of the graph.
3). Amplitude of the graph is = (2-0)/2 = 1
4). Phase shift of the given graph = 0
The graph satisfying all properties is option B. y = cosx + 1
