You have added -13 to every function value, so every point on the graph is 13 "spaces" lower. The y-intercept is one such point, so ...

<em>Comment on notation</em>
In plain text an exponent is preceded by a caret (^). If the exponent has arithmetic involved (addition, subtraction, multiplication, division), then the entire exponent needs to be enclosed in parentheses. When an exponential term that has a constant base is multiplied by another constant, then some sort of multiplication indicator is useful. Your expressions might be written ...
... f(x) = 4·2^x
... f(x) = 4·2^x - 13 . . . . . . or, better, f(x) = 4(2^x) - 13 . . so it is clear -13 is not part of the exponent

Answer:
4.45 m
Step-by-step explanation:
From the question above,
Median is the middle of a given data of distribution.
Given:
Data : 7.1, 21.5, 1.8, 1.6.
Rearrenging the date in decending order
21.5, 7.1, 1.8, 1.6.
From the above,
median = (n+1)th/2
median = (7.1+1.8)/2
median = 8.9/2
median = 4.45 m.
Hence the median height = 4.45 m
There's a theorem for this: the angle made by two intersecting secants of a circle has a measure equal to half the difference of the arcs the secants intercept. In this case,
<em>x</em> = (130° - 30°) / 2 = 50°
