Question

Match each given domain of the function f(x)=2/2.5 with its corresponding range.

Answer 1

$f(x)=\dffrac{x}{2.5}$

$\text{Domain:}\{40,\ 45,\ 50,\ 55,\ 60\}\\\\f(40)=\dfrac{40}{2.5}=16\\\\\text{Range:}\{16,\ 18,\ 20,\ 22,\ 24\}\\----------------------------\\\text{Domain:}\{52,\ 56,\ 63,\ 67,\ 71\}\\\\f(16)=\dfrac{52}{2.5}=20.8\\\\\text{Range:}\{20.8,\ 22.4,\ 25.2,\ 26.8,\ 28.4\}\\----------------------------$

$\text{Domain:}\{37,\ 46,\ 49,\ 55,\ 57\}\\\\f(37)=\dfrac{37}{2.5}=14.8\\\\\text{Range:}\{14.8,\ 18.4,\ 19.6,\ 22,\ 22.8\}\\----------------------------\\\text{Domain:}\{44,\ 51,\ 59,\ 66,\ 73\}\\\\f(44)=\dfrac{44}{2.5}=17.6\\\\\text{Range:}\{17.6,\ 20.4,\ 23.6,\ 26.4,\ 29.2\}\\----------------------------$
