Hi can you please explain and solve thank you

Answer 1

The table y values represent an exponential function. The fourth y term divided by the third y term equals 2. The third y term divided by the second y term equals 2 and so on. The constant ratio is therefore 2. The explicit formula for an exponential function is in the form y = ab^x, where “a” is a constant and “b” is the constant ratio. So the equation is y = a2^x, an exponential equation with a constant ratio of 2. The answer is C
