You must understand how to get values from functions. Use the slider bar to select values for x and observe how the values of the functions f, g, h and j change accordingly.
f(x) = 2x+1
Choose x:

f(x) =

g(x) = 3x2
Choose x:

g(x) =

h(x) =12/x
Choose x:

h(x) =

j(x) =10-2x
Choose x:

j(x) =


Can you find two values of x that makes f(x) and g(x) equal?
f(x) = 2x+12, g(x) = 2x2
Choose x:
f(x) = g(x) =
