It is close to 200 because 150 or above would be rounded to 200. Below 150 would be 100
You would do percent of change.
meaning you would subract 65 and 50 to get 15. then you would put 15 over 50 (as a fraction) then equals r/100. then you would cross multiply to get r.
orginal:50
new:65
65-50=15
15/50=r/100
15r=5000
then divide by 15 to get r
is strictly increasing on [0, 5], so

and

so the integral is bounded between

Answer:
The points are (-1, 1), (2, 7), (1, -1), (3, 0)
Step-by-step explanation:
Let us solve the question
∵ f(x) = y
∴ The coordinates of the point are (x, y)
→ Let us use this fact to find the coordinates of each point
∵ f(-1) = 1
∴ x = -1 and y = 1
∴ The coordinates of the point are (-1, 1)
∵ f(2) = 7
∴ x = 2 and y = 7
∴ The coordinates of the point are (2, 7)
∵ f(1) = -1
∴ x = 1 and y = -1
∴ The coordinates of the point are (1, -1)
∵ f(3) = 0
∴ x = 3 and y = 0
∴ The coordinates of the point are (3, 0)
