in order to solve which will have the fastest rate, then we will assume a value of x. so let assume that x = 100
a.) h(x) = 6x^2+1
h(x) = 6(100)^2 + 1
h(x) = 60001
b. f(x) = 9x+14
f(x) = 9(100) + 14
f(x) = 914
c. g(x) = 4x
g(x) = 4(100)
g(x) = 400
d. j(x) = 200x + 5
j(x) = 200(100) + 5
j(x) = 200005
so the answer is
j(x) = 200x + 5
