A quadratic function f(x) is hidden from view. You must find all intervals where f(x) is increasing. Choose the form of the quadratic function f(x) that you would like to see in order to answer the question most efficiently. Standard: f(x)=-3x^{2}+18x+21
Vertex: f(x)=-3(x-3)^{2}+48
Factored: f(x)=-3(x-7)(x+1)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
