Final answer:
The value of a in the equation y=a*2ˣ is equal to the value of y when x = 0.
Step-by-step explanation:
The given equation represents an exponential growth function. The general form of an exponential function is y = ab^x, where a is the initial value and b is the growth factor. In this case, we are given the equation y = a*2^x. To find the value of a that completes the equation, we need to know the initial value of y when x = 0.
When x = 0, the equation becomes y = a*2^0 = a*1 = a. Therefore, the value of a is equal to the value of y when x = 0.
For example, if y = 5 when x = 0, then a = 5.
