we need know the graph of f(x) = a^x first both a>0 , or a<0
then
a) x- and y-intercepts
x=0 , y =1 => y-intercepts
y =0 => never, no x-intercept
b) domain and range
domain :all real
range : (0,∞)
c) intervals of increase or decrease
decrease (∞,-∞)
d) minimum or maximum point
no min, no,max,
e) equation of the horizontal asymptote
y = 0
