The domain of y = -4x is all real numbers.
The domain can be anything you like: a single element, all real numbers, all complex numbers, etc.
The domain is anything you want it to be. You could define the domain to be integer values only, or it could be {-3, -2.5, .2, 0, sqrt(7), 9}.
The answer depends on the domain - the set of values that x can take..
It is the infinite set of points of the form [x, (4x+9)/7] for all value of x in its domain.
f(x) = 8x - 4x2 - 5x - 36 = -4x2 + 3x - 36 The domain for f(x) can be the whole of the Complex field or any subset.
The domain of y = -4x is all real numbers.
-18
Depends on what Fx is.
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
Since it is a polynomial we know right away the domain is all real numbers.
y = 3x + 2x^2 + k where k is any number
The domain is what you DONATE to the equation. So, f(x)=4x-2. Let 18=4x-2. Add 2 to both sides. 4x=20 then divide each side by 4. x=5. That would be your answer.
The domain can be anything you like: a single element, all real numbers, all complex numbers, etc.
f(X)=4x+4 is the exact same thing as y=4x+4. it simply means the function of x is 4x+4. also, any other letter can be used in place of f. f(X)=4x+4 is the same as g(x)=4x+4.
x = ¼x^4 + 4x + k where k can be any number
The domain is anything you want it to be. You could define the domain to be integer values only, or it could be {-3, -2.5, .2, 0, sqrt(7), 9}.
