q.2
what is f(-5)?

Option C:

The value of f(–5) is –15.

Solution:

The value of f(x) is depend on the value of x.

Here x is independent variable and f(x) is the dependent variable.

To find the value of f(–5):

f(–5) means, we should find the value of our function when x equals –5.

In the table, see the value of f(x) corresponding to the value of x = –5.

In third row, x is –5.

So, f(x) is –15.

Hence the value of f(–5) is –15.

Option C is the correct answer.

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
