D. x

Answer 1

Hello,

answer A

5*6.8^0=5*1=5

Answer 2

Answer: A. 5

Explanation:

The given exponential equation:

`y=5(6.8)^x`

To calculate the y intercept , we need to substitute x =0 , the given equation, we get

`y=5(6.8)^0\\\\\Rightarrow\ y=5(1)......................\text{Since}\ a^0=1\\\\\Rightarrow y=5`

Hence, the y intercept of the given exponential equation = 5.
