Question

If g(x) = 2x − 3, then what is the value of g(2) − g(3) ?

Answer 1

\[\Large g(\color{royalblue}{x})=2\color{royalblue}{x}-3\]
Plugging 2 in gives us,\[\Large g(\color{royalblue}{2})=2\cdot\color{royalblue}{2}-3\]
Understand how that works? :)

Answer 2

\[\Large g(\color{royalblue}{2})=1\]

Can you figure out g(3)?\[\Large g(\color{royalblue}{2})-g(\color{royalblue}{3}) \qquad=\qquad 1-g(\color{royalblue}{3})\]
