Domain range and function

Mathematics
1 answer:
aleksandrvk [35]3 years ago
6 0

Step-by-step explanation:

Look at the picture.

\bold{DOMAIN:}\ 3\leq x

Function? NOT, because for x∈(3, 5) the relation has two values of y.

The vertical line test.

If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function (picture 2).

Doctors sometimes use this formula to calculate how much medicine to give a child. A child who is 4 years old needs some medicin
AnnyKZ [126]

Answer:

A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity

Step-by-step explanation:

Medications are available in multiple concentrations, therefore orders written in "mL" rather than "mg" are not acceptable and require further clarification.

...

Example 2.

Step 1. Calculate the dose in mg: 18 kg × 100 mg/kg/day = 1800 mg/day

Step 2. Divide the dose by the frequency: 1800 mg/day ÷ 1 (daily) = 1800 mg/dose
