Consider the function represented by the equation y – x – 4 = 0. what is the equation written in function notation, with x as the independent variable?

Writing an equation in function notation, with x as the independent variable is the same as solving the equation for y.

So, we start with

and we move to the right hand side, i.e. we add to both sides:

$450 i think. hope this ☺

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
