Answer:
(See explanation)
Step-by-step explanation:
The function is:

Its simplified form is presented hereafter:

The resultant expression is a linear function, first-order polynomial, whose domain and range are the set of the real numbers.
Answer:
Greater.
Step-by-step explanation:
The in the function
, the square root term
has to give a real number if
is to be real. This can only happen if
because if
then
will give a complex number and therefore
will not be real.
Thus, the domain for f(x) is all real numbers<em><u> greater</u></em><u> </u>than or equal to 2.
Answer: The shoe size would be recommended for a four-month-old baby is equal to 1
Step-by-step explanation:
Since, according to the given figure,
Here, x represents age of baby (in month) while y represents shoe size.
And for babies ,
the shoe size = 0
the shoe size = 1
the shoe size = 2
the shoe size = 3
the shoe size = 4
thus, from the above we can say that, the shoe size of the baby who is 4 month old is 1.
90 inches 18 times 5 is 90 and 30 times 3 is 90 so the lowest point which they will be at the height is 90 inches
