Answer:
-130.8
Step-by-step explanation:
The average of the two slope values is ...
(-148.8 -112.8)/2 = -261.6/2 = -130.8
The slope of the tangent line at t=15 is approximately -130.8.
Answer:
not sure
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Take a look at the graph starting from the left. You’ll see that on the horizontal line, the graph starts at -4 then starts to go downward until it gets to -2 and it starts going up after that so your first interval is (-4, -2). The line increases from -2 to 2 and then it starts sliding downward again from 2 to 4 so your second decreasing interval is (2, 4).
Answer:
Statements A and D
Step-by-step explanation:
A. Since all of the values surrounding x = 0.5 reflect across that point, there is a line of symmetry at x = 0.5
B. This is not a y intercept since in the point (-12,0) the x value is not zero and at y intercepts, it should be zero.
C. Same thing from statement B, the y value for the x intercepys should be zero, not 4 or -3.
D. To help visualize this, take the slope of the secant line from x = -4 to x = 0.
(8 - (-10))/(-4 - 0) = 18/(-4) or -9/2. Since the slop is negative, the function is decreasing on this interval.
