What's wrong with my question... Is it right?

The graph shows the charges for a health club in a month. make a function table for the input-output values. writes an equation that can be used to find the total charge y for the number of x classes

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

In which direction does the left side of the graph of this function point? a(x) = 3x - x2 + 4x - 2
