If h(x) is a function whose domain is [-8,8], and g(x)=h(2x^2), then the domain of g(x) is an interval of what width?
Within the domain [-8,8], the smallest value of g(x) is 0 which occurs when x = 0.
The largest value of g(x) is 128, which occurs both when x = -8 and x = 8.
The interval has a width of 128.
