Answer:
Third Option
Step-by-step explanation:
We know that the function is defined as
. Since the denominator is
then we know that
when
We also know that the division by 0 is not defined. Therefore, the limit of when "x" tends to
is infinite.
The function is the inverse of
By definition, if we have a function f(x), its domain will be equal to the range of its inverse function . If
, then
This also happens for the function
If when then when
Then, the answer is:
Answer:
Measure of ∠BCP is 36°
Step-by-step explanation:
Given the circle in which measure of arc BC is 72°
we have to find the measure of angle BCP.
m∠BOC=∠2=72°
By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.
∴ ∠2=2∠1 ⇒ 72=2∠1
⇒ ∠1=36°
By alternate segment theorem which states that
The angle formed between a chord and a tangent through one of the end points of chord is equals to angle in alternate segment.
⇒ ∠3=∠1=36°
Hence, measure of ∠BCP is 36°
Option D is correct
