For this case we have that, by definition, the domain of a function is given by all the values for which the function is defined.
Having said that, we have the following function:
It is not defined when the denominator is equal to 0. That is:
Thus, the domain of r (x) is given by all real numbers except 1.
Answer:
all real numbers except 1.
Option A
Answer:
3/16 or 0.1875
Step-by-step explanation:
3/4 - ((3/8)/2/3))
= 3/4 - 3/8 * 3/2
= 3/4 - 9/16
= 12/16 - 9/16
= 3/16 or 0.1875
Hope this help you :3
Explicit Functiony = f(x) is said to define y explicitly as a function of x because the variable y appears alone on one side of the equation and does not appear at all on the other side.

Assign letters to all quantities that vary with time and any others that seem relevant to the problem. Give a definition for each letter.
2. Identify the rates of change that are known and the rate of change that is to be found. Interpret each rate as a derivative.
3. Find an equation that relates the variables whose rates of change were identified in Step 2. To do this, it will often be helpful to draw an appropriately labeled figure that illustrates the relationship.
4. Differentiate both sides of the equation obtained in Step 3 with respect to time to produce a relationship between the known rates of change and the unknown rate of change.
5. After completing Step 4, substitute all known values for the rates of change and the variables, and then solve for the unknown rate of change.</span>Local Linear Approximation formula<span>f(x) ≈ f(x₀) + f'(x₀)(x - x₀)

Answer:
The cost of one hot dog is $2.50
Step-by-step explanation:
You need to subtract $3.20 from $18.20 to get $15.00. Then you need to divide $15.00 by 6 to get $2.50.
