What number is not part of the domain of f(x) = 3/x+5 how can you tell

Domain of a Function is a Set of Values under which the Function is defined or a Set of Values which satisfy the respective Function.

The Given Function is : f(x) =

When function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)

As the given function is a Fraction which contains the variable x in it. The given Function is not defined when x + 5 = 0

⇒ The Given Function is not Defined when x = -5

Because at x = -5, The Function tends to ∞ and becomes undefinable

So, As the Domain is the set of Values which satisfies the Function, -5 cannot be the part of the Domain

-5 is the Number which is not part of the Domain

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
