Determine x when f(x) = 100
x = ______

Answer 1

Answer:

x=3.33

Step-by-step explanation:

$fx = 100 \: and \: f = 10(3) \\ so \: f = 30$

$to \: find \: fx \: divide \: 100 \: by \: 30 \\ so \: fx \: will \: be \: 100 \div 3$

$= 3.3333....... \\ then \: round \: off \: to \: 2s.f$

$3.3333.... to \: 2s.f \: = 3.33 \:$
