Answer:
B.
Step-by-step explanation:
5x - 3 = y then 5x = y + 3 then x = (y + 3)/5
then the inverse function of f is : (x+3)/5
45
f(x)=2^6x-19
f(1)=2^(6(1))-19=2^(6)-19=2^6-19=64-19=45
2.178 * 10^-11 is the final answer you seek
this is correct on plato/edmentum
27
find square root of 81 and multiply by 3
9 x 3 = 27
