Question

Cho hàm số y = f(x) = 20/x

tính f(5) , f(10) , f (4)

Answer 1

\(f\left(x\right)=\frac{20}{x}\)

\(\Rightarrow f\left(5\right)=\frac{20}{5}=4\)

\(\Rightarrow f\left(10\right)=\frac{20}{10}=2\)

\(\Rightarrow f\left(4\right)=\frac{20}{4}=5\)

Answer 2

4;2;5 nah ban

Answer 3

f(5)/20/5=4

f(10)=20/10=2

f(4)=20/4=5
