Which function and domain could represent the given
graph?
Of(x) = 1 - [x]; -3 O f(x) = 1 + [x]; -3 SXS3
f(x) = -[x]; -3 5x53
O f(x) = (x); -3

part a: 1.08

part b: 27.59

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
