Question

se f(x)=x2+1/5,então f(2/5) é igual a? ​

Answer 1

Resposta:

$f(x)=x^2+{1\over5}\\ \\ f({2\over5})=({2\over5})^2+{1\over5}\\ \\ f({2\over5})={4\over25}+{1\over5}\\ \\ f({2\over5})={4+5\over25}\\ \\ f({2\over5})={9\over25}$

Answer 2

Resposta:

f (2/5) = (2/5)^2 + (1/5)

f (2/5) = (4/25) + (1/5)

f (2/5) = (4 + 5)/25

f (2/5) = 9/25
