Answer:
D. f(x) = -|x+4| +3
The graph is flipped over the x-axis (facing down) so there's a negative sign in front of the function. It's shifted to the left 4 units so it'll be |x+4|. Finally, it's shifted up 3 units so it'll be +3 outside of the absolute bracket.
NOTE: if there's a change to the x value then it's inside the bracket or parenthesis, if there's a change to the y value then it's outside of the bracket or parenthesis

Answer: B) -3/8</h3>
Explanation:
When multiplying fractions, we multiply the numerators together, and the denominators are handled separately.
The numerators in this case are -1 and 3. They multiply to -3
The denominators multiply to 2*4 = 8
So that's how we end up with -3/8 as the final answer
This fraction cannot be reduced any further, because 3 and have 8 no factors (other than 1) in common.
Given:
d(t) = 0.8t²
d(5) = 0.8*5² = 0.8 * 25 = 20
d(10) = 0.8*10² = 0.8 * 100 = 80
Average speed = distance traveled / time of travel
Average speed = 20 meters / 5 seconds = 4 meters per second
Average speed = 80 meters / 10 seconds = 8 meters per second
4 mps + 8 mps = 12 mps
12 mps / 2 = 6 mps the average speed in meters per second between 5 and 10 seconds.
