The range of which function includes –4?
y = StartRoot x EndRoot minus 5
y = StartRoot x EndRoot + 5
y = StartRoot x + 5 EndRoot
y = StartRoot x minus 5 EndRoot

Correct option A) y = StartRoot x EndRoot minus 5

Step-by-step explanation:

Here we have , to find which of the following function includes range -4 ! Let's find out range for each function :

y = StartRoot x EndRoot minus 5

Equation is given as :

⇒

At x=1 , we have

⇒

⇒

Hence , This function range includes -4 .

y = StartRoot x EndRoot + 5

Equation is :

⇒

We know that for every value of x , Hence minimum value of this function is :

⇒

Hence , This  function range doesn't includes -4

y = StartRoot x + 5 EndRoot

Equation is :

⇒

We know that for every value of x , Hence minimum value of this function is :

⇒

Hence , This  function range doesn't includes -4

y = StartRoot x minus 5 EndRoot

Equation is :

⇒

We know that for every value of x , Hence minimum value of this function is :

⇒

Hence , This  function range doesn't includes -4.
