Answer 1

Explanation:

Exponential equation:

`\boxed{y=a*b^(x)}`

Choose the point whose x-coordiante is 0, so that we can find the value of a. (0,2)

`2 = a*b^0\\\\2 = a*1 \ [\text{\bf any \ variable raised to 0 is 1}]`

`\sf \boxed{a = 2}`

Now, choose (1 , 1) and find the value of b

`1 = 2*b^(1)\\\\1 = 2*b\\\\(1)/(2)=b`

Exponential equation:

`\bf \boxed{y =2* \left((1)/(2)\right)^(x)}`
