the output value = 1
Step-by-step explanation:
The exponential function:
y = 12.5 ^x
when x = 0, y = ?
we insert the value of x in the exponential function to get y:
![y=12.5^0](https://img.qammunity.org/2023/formulas/mathematics/college/vn46ryp33r5kssigbznze388h6gh1b7trt.png)
Note: Any number raised to a power of zero = 1
Hence, y = 12.5^0 = 1
Therefore, the output value = 1
