Question

Find the function and write domain in interval notation interger

Answer 1

`(p\circ n)(x)=x^2-7x+10`

Step-by-step explanation:

we know that

`p(x)=x^3+3x`

Putting in the value of n(x) in P(x) gives

`(x-5)^2+3(x-5)`

expanding the above gives

`x^2-10x+25+3x-15`
`=x^2-7x+10`

Hence,

`(p\circ n)(x)=x^2-7x+10`

which is our answer!
