HELP!?! Without graphing, state the following for the graph of the exponential function:

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


10pts xoxox

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
