If a graph is rising on the left and falling on the right, which function would the graph belong to?
a: f(x) = x3 + 2x + 3
b: f(x) = –x4 + 2x2 + 1
c: f(x) = –x3 + 4x

Will give let f(x)=2x and g(x)=[tex]2^{x}[/tex] graph the functions on the same coordinate plane. what are the solutions to the equation f(x)=g(x) ? enter your answers in the boxes x=[? ] or x=[? ]
