y =0 => never,range : (0,decrease (∞,no min, no,max,......
y= (2/7)^x

a) x- and y-intercepts
b) domain and range
c) intervals of increase or decrease
d) minimum or maximum point
e) equation of the horizontal asymptote

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
