If (f:\mathbb{R}\to\mathbb{R}) and (f(x)=x+10), what does comparing (f(4)) and (f(5)) show?

Answer and explanation

Correct answer: Different inputs give different values

Step 1: (f(4)=14) and (f(5)=15). Step 2: Different inputs give different values. Step 3: In such a linear function, adding the same number preserves order and one-one property.
