f\left(-2\right)=0,25
Calculate 0,5 to the power of 2 and get 0,25.
f=\frac{0,25}{-2}
Divide both sides by -2.
f=\frac{25}{-200}
Expand \frac{0,25}{-2} by multiplying both numerator and the denominator by 100.
f=-\frac{1}{8}
Reduce the fraction \frac{25}{-200} to lowest terms by extracting and canceling out 25.
