Correct option A) y = StartRoot x EndRoot minus 5
<u>Step-by-step explanation:</u>
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.
