Answer:
Step-by-step explanation:
The standard form of an exponential function is
[tex]y=a(b)^x[/tex] , where a is the initial value and b is the growth factor.
You will always find your initial value at the y value where x = 0. From your table where x = 0 and y = 1/2:
[tex]\frac{1}{2}=a(b)^0[/tex]
Any number or variable raised to the power of 0 = 1, therefore
[tex]\frac{1}{2}=a(1)[/tex] which gives us an initial value, a, of 1/2.
