Find the value of each of the following ...

Find the value of each of the following :
`(i) p(x)=3x+7 " at" x=1 " " (ii) q(y)=y^(3)-3y^(2)+sqrt(3) " at" y=1`
(iii)`p(a)=a^(4)+6a^(2)-6a+3` at a=m

Text Solution

Verified by Experts

(i) p(x)=3x+7
`implies p(1)=3xx1+7=10`
(ii) `q(y)=y^(3)=3y^(2)+sqrt(3)`
`implies q(1)=1^(3)-3xx1^(2)+sqrt(3)=1-3+sqrt(3)=-2+sqrt(3)`
(iii) `p(a)=a^(4)+6a^(2)-6a+3`
`implies p(m)=m^(4)+6m^(2)-6m+3`
