Simplify. consider all the cases.
example:
x−5=

x−5, if x> 5
0, if x=5
5−x, if x< 5

2x+7

a) if x > , then 2x + 7 =
b)if x = , then 2x + 7 =
c) if x < , then 2x + 7 =
(x−4)+7

if x > , then (x − 4) + 7 =
if x = , then (x − 4) + 7 =
if x < , then (x − 4) + 7 =

7−(x−7)

if x > , then 7 − (x − 7) =
if x = , then 7 − (x − 7) =
if x < , then 7 − (x − 7) =

7−(12−x)

if x > , then 7 − (12 − x)=
if x = , then 7 − (12 − x =
if x < , then 7 − (12 − x)=

(x, y)→(x − 8, y − 7)

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
