a)f (1) =\(\frac{1}{3}\) . 1 = \(\frac{1}{3}\)
f (-3) =\(\frac{1}{3}\) . (-3) = -1
b) f (-6) = \(\frac{1}{3}\) . (-6) =-2
f (\(\frac{1}{2}\)) = \(\frac{1}{3}\) . \(\frac{1}{2}\) = \(\frac{1}{6}\)
Hàm số \(y=f\left(x\right)=\frac{1}{3}x\)
a) \(f\left(1\right)=\frac{1}{3}.1\)
\(f\left(1\right)=\frac{1}{3}.\)
\(f\left(-3\right)=\frac{1}{3}.\left(-3\right)\)
\(f\left(-3\right)=-1.\)
Chúc bạn học tốt!
Ta có :
a, f(1) = 1/3. 1 = 1/3
b, f(-3) = 1/3 . (-3) = (-1)
c, f(-6) = 1/3 . (-6) = (-2)
d, f(1/2) = 1/3 . 1/2 = 1/6
