Which is an equation of the graph shown in the diagram? Pls help will mark brainliest. :)

B

Step-by-step explanation:

The graph is symmetrical about the y- axis thus has equation

y = ax² + c ( c is the y- intercept )

Here c = 4 and

y = ax² + 4

Since the graph has a maximum and opens down the a < 1

y = - x² + 4 → B

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.
