Solve the Problem $D(x)=5400(4)^{x}$ , Where $x$ Is the Time in Milliseconds of the Lightning Strike

Solve the problem.
-The number of dislocated electric impulses per cubic inch in a transformer when lightning strikes is given by $D(x) =5400(4) ^{x}$ , where $x$ is the time in milliseconds of the lightning strike. Find the number of dislocated impulses at $\mathrm{x}=0$ and $\mathrm{x}=5$ .

A) $21,600,5,529,600$
B) $5400,1,382,400$
C) $5400,5,529,600$
D) $5400,108,000$
