1)the following function defines a recursive sequence: f(0) = -3 f(1) = 6 f(n) = -2•f(n -1) - f(n - 2); for n > 1 which of the following sequences is defined by this recursive function? -3, 6, -9, -12, … -3, 20, -95, 480, … -3, 6, -9, 12, … -3, -20, -95, -480, … 2) choose the slope-intercept equation of the line that passes through the point (-2, 2) and is parallel to y = 4x + 7. y = 4x + 10 y = x + y = -4x - 6 y = - x + 3)the table below represents the distance a person runs as a function of time: time (second) x distance (meters) f (x) 10 60 13 78 16 96 19 114 the average rate of change of the function between x = 10 to x = 16 is m/s and represents the person's speed. 4)choose the graph below that has slope of zero.

1) -3, 6, -9, 12...
f(2) = -2*6 - (-3) = -9
f(3) = -2*-9 - (6) = 12

2) 2) Choose the slope-intercept equation of the line that passes through the point (-2, 2) and is parallel to y = 4x + 7.
Slope equals 4, since it's parallel. Substituting...
2 = 4*-2 + b          Add 8 to both sides
10 = b 
y= 4x + 10

3)Question is poorly transcribed, but assuming the points are (10, 60) and (16, 96):
 Average rate of change = (96-60) / (16-10) = 36 / 6 = 6m/s. 

4) A slope of zero means that y does not change with x. This means y is the same for any x value, so y is a horizontal line.
The third graph, the one where y= -6, is the correct answer.
