If a function `g={(1,1),(2,3),(3,5),(4,7)}` is described by `g(x)=alphax+beta,` find the values of `alphaa n dbetadot`

Text Solution

Verified by Experts

`g={(1,1),(2,3),(3,5),(4,7)}`

Here, each element of domain has unique image. So, `g` is a function. Now, given that, `g(x)=alpha x+beta`

`g(1)=1 `

`Rightarrow alpha+beta=1 cdots-(1) `

`g(2)=34 `

`Rightarrow 2 alpha+beta=3 cdots-(2)`
