Question

giúp tớ làm bài này với các bạn ơi plss!

Answer 1

f(2)=2\(^2\)+5
f(2)=9

Answer 2

f(-\(\dfrac{1}{3}\))=(\(-\dfrac{1}{3}\))\(^2\)+5
f(-\(\dfrac{1}{3}\))=\(\dfrac{1}{9}\)+5
f(-\(\dfrac{1}{3}\))=\(\dfrac{46}{9}\)

Answer 3

chúc bạn học giỏi nha

Answer 4

f(2) = \(2^2+5=4+5=9\)

f\(\left(\dfrac{-1}{3}\right)=\left(\dfrac{-1}{3}\right)^2+5=\dfrac{1}{9}+5=\dfrac{46}{9}\)
