Graphs of Exponential Functions An exponential function is a mathematical function in the form of f (x) = a x where x is an exponent and a is a constant (also known as the base) and where a ∈ R + and ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...
