Question 1204988
Find the exponential function 

{{{f(x) = a^x }}}

passes through the point ({{{2}}},{{{25}}}) 
 has a y-intercept of {{{1}}}


use given point to calculate {{{a}}}
 
{{{25= a^2}}}

{{{a=5}}} 

the exponential function is:

{{{f(x) = 5^x }}} or {{{y= 5^x }}}


{{{ graph( 600, 600, -5, 5, -5, 5, 5^x, 5^x) }}}
