A virus multiplies by a factor of 10 every 4 days. If there are 12 individuals initially affected, what is the exponential equation for the number of infected individuals, y, after x days?(1 point)Responsesy=12⋅(40)xy is equal to 12 times 40 to the x th powery=10⋅(12)xy is equal to 10 times 12 to the x th powery=12⋅(10)xy is equal to 12 times 10 to the x th powery=12⋅(4)x\

y = 12·10^(x/4)

Reason: every 4 days the count is multiplied by 10, so after x days there are 10^(x/4) four-day intervals. Equivalently y = 12·e^{(ln 10 / 4) x}.
