Determine what kind of function might be used as a model for the data.
A. Linear: f(x) = mx + b B. Quadratic: f(x) = ax2 + bx + c, a < 0 C. Quadratic: f(x) = ax2 + bx + c, a > 0 D. Polynomial, but neither quadratic nor linear
Write the function as the composition of two functions f and g such that y = f[g(x)]).y = (x1/2 + 3)3 + 6(x1/2 + 3) 2 - 10
A. f(x) = x3 + 6x2 - 10, g(x) = x1/2 + 3 B. f(x) = x1/2 + 3, g(x) = x3 + 6x2 - 10 C. f(x) = (x + 3)3 + 6(x + 3) 2 - 10, g(x) = x1/2 + 3 D. f(x) = (x + 3)3 + 6x2 - 10, g(x) = x1/2
