Function Problem

<p>f(x)= a^x then
A. f(x+y)= f(x)+f(y)
B. f(x+y)= f(x)f(y)
C. f(x-y)= f(x)-f(y)
D.f(xy)= f(x)f(y)
E.f(x/y)= f(x)/f(y)</p>

<p>i just can't seem to understand this problem. Any way someone could explain it to me please thanks!!!</p>

<p>Agree with peeinthesink.</p>

I guess the post by "peeinthesink" was deleted.</p>

<p>i think this problem tests you on exponent props when you multiply / divide two expressions with the same base.
a^x times a^y gets you a^(x+y)
a^x divided by a^y gets you a^(x-y)</p>

<p>Yeah, answer is B.</p>
