The graphs of two functions f and g are shown below.
The graphs of the functions f of x equals negative zero point five x raised to the power of four plus two x squared (the solid blue curve) and g of x equals zero point five x raised to the power of four minus two x squared (the dashed red curve) are plotted on the same graph.
a. Write a function formula for g using the function f.
g(x) =
b. Write a function formula for f using the function g.
f(x) =
