QuestionPart 1 of 4 (a) Show that f(x)=3x+3f(x)=3 x+3 defines a one-to-one function.
A function is one-to-one if it can be shown that if f(a)=f(b)f(a)=f(b), then □=□\square=\square. Assume f(a)=f(b)f(a)=f(b).

Studdy Solution
Divide both sides by 3 to solve for a a and b b :
a=b a = b
This shows that if f(a)=f(b) f(a) = f(b) , then a=b a = b , which proves that the function is one-to-one.
