Answer:
A = 7 and C = 2
Step-by-step explanation:
the constant C represents the average value of the wave. To find its value, we need to calculate the average between the y-coordinates of the highest and the lowest point.
The highest point has y = 9, and the lowest point has y = -5, so we have:
C = (9 - 5)/2 = 4/2 = 2
The value of A represents the increase in the amplitude of the wave.
For A = 1, the amplitude is 2 (lowest point = average - 1, highest point = average + 1)
So, in this case, the amplitude is the difference in the y-coordinates of the highest and the lowest point, and A is equal half the amplitude:
A = (9 - (-5)) / 2 = (9 + 5)/2 = 14/2 = 7

Answer:
Step-by-step explanation:
x^2 - 17x - 60
(x - 20)(x + 3)
x^2 + 3x - 20x - 60
x^2 - 17x - 60
(x + 20) is not one of the factors
using F.O.I.L., it would have been
x^2 + 17x - 60
