Exponents and Logarithms
Exponential graphs
f(x) = k.ax+p + q
Parameter a:
The base, a, is always positive.
a>0
Increasing graph, base is an improper fraction.
0<a<1
Decreasing graph, base is a proper fraction.
Parameter p:
= horizontal shift
, Parameter q:
= vertical shift
Asymptote: y = q
Domain: x ∈ R
Range: y ∈ (q ; ∞)
