The parent function f(x) = log3x has been transformed by reflecting it over the x-axis, stretching it vertically by a factor of two and shifting it down three units. which function is representative of this transformation?

Step-by-step explanation:

In order to stretch a function you need to multiply by a factor, in this case is two.

In order to shift your function vertically, you need to add or subtract a number, adding you shift up, subtracting you shift down. That's why wee subtract the 3 units, because it says 'shifting down'.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
