The following table shows the number of feet a bird flies above the ground as a function of time:
time (in seconds) x distance above ground (in feet) f(x)
0 21
2 18
4 15
6 12
8 9

find and interpret the meaning of the x-intercept in this scenario.
a. (21, 0); the time it takes for the bird to reach the ground
b.(14, 0); the time it takes the bird to reach its highest point
c. (21, 0); the time it takes the bird to reach its highest point
d. (14, 0); the time it takes for the bird to reach the ground

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
