Exponential function

Question

Graph f(x)=3^-x over the interval [-2,2]

Answer 1

y = 3^-x is an exponential curve . limit the domain to x=-2 to x=2

'that gives you points (-2,9), (0,1) and (2, 1/9)

plot those 3 points and connect them with a smooth exponential curve, all downhill, shaped like the first part of the slope a skate boarder uses

horizontal asymptote is y=0

range is [1/9 to 9]

Answer 2
