Question

3 + 2xThe function g is defined by g(x) =-5+xFind g (2a).g (2a) =

Answer 1

Consider the given function,

`g(x)=(3+2x)/(-5+x)`

Replace 'x' by '2a' in the given expression,

`\begin{gathered} g(2a)=(3+2(2a))/(-5+2a) \\ g(2a)=(3+4a)/(-5+2a) \end{gathered}`

Thus, the required function is,

`g(2a)=(3+4a)/(-5+2a)`
