Question

Find the indicted outputs for f(x)=5 to the second power -2x
f(0)=
f(-1)=
f(2)=

Answer 1

If it was 0, then it would be 1 because anything raised to the 0 power is 1.
-1*-2=2, so it would be 5^2=25
-2*2=-4, so 5 will be in the denominator. You will get 1/(5^4)

Answer 2

So, f(0)= 1
f(-1)= 25
f(2)=?
