Question 1187184
.
Find a value a > 0 so that the graph of the exponential function f(x) = ax^2 contains the points (2, 1/4).
~~~~~~~~~~~~~~~~~~~~


<pre>
You need to have  f(2) = 1/4,  or  {{{a*2^2}}} = {{{1/4}}}.


From this equation,  a = {{{1/(4*4)}}} = {{{1/16}}}.


<U>ANSWER</U>.  The value of "a" must be  {{{1/4}}}.
