Question

Does this equation y=1/4^x crosses the x-axis?

Why? and How? Need explanations

Answer 1

I assume that this is y = (1/4)^x is that right?

Answer 2

yes

Answer 3

it dosnt crosses the x-axis
coz its always positive function {f(x)>0}
there is no
interval [a,b]
such that f(a) >0 , f(b) <0
other wise
limit f(x) = 0 , when x goes to infinite
