Question

Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim. A Find the domain and the range of this function.Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim. Find the domain and the range of this function.

Answer 1

The domain and the range of this function are the set of all real numbers

Finding the domain and the range of this function.

From the question, we have the following parameters that can be used in our computation:

• A number N
• Multiplied by 5
• added to 7.
• Result R

From the above, we have the function to be

R = 5 * N + 7

R = 5N + 7

The function above is a linear function

This means that it can take any real value as its input or output

Hence, the domain and the range of this function are the set of all real numbers

Question

Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim. Find the domain and the range of this function.

Answer 2

-∞ < x < ∞

-∞ < y <∞

Explanation:

Suppose number is x

When Ann multiple it by 5 and added 7 to it the equation will be

= 5x + 7

The domain of a function is the complete set of possible values of the independent variable.

The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)

Domain:

-∞ < x < ∞ Set of all integers

Range :

-∞ < y < ∞ Set of all integers
