Best Answer

The domain can be any set that you like: from the set of complex numbers down to the set comprising just one number, eg {7.39}.

At x = 3, the value of F(x) = 3x + 2 is the value 11, which graphs to the point (3, 11).

at first draw the graph of fx, then shift the graph along -ve x-axis 21 unit

The composite function f of g is also expressed as f(g(x)). In this case, it would be 12(3x), or 36x.

Yes.

Look for points where the denominator is equal to zero. In other words, solve the equation: denominator = 0

The function f(x) = 3x + 2 can take any real value, so the question does not seem to make any sense.

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.

please elaborate your question

- 2 makes this zero and provides the vertical asymptote. So, from - infinity to - 2 and from - 2 to positive infinity

The domain can be anything you like: a single element, all real numbers, all complex numbers, etc.

y = 3x + 2x^2 + k where k is any number

fx=3x-5 f=(3x-5)/x f2=(6x-10)/x /=divide

If it were written in a book of some sort, fx or f(x) is read aloud as "f or x". "f" is a function of some variable, "x". By function it means something happens to x e.g. x2 or 3x+4.

The range is the all the possible y-values for the function. f(x)=2-3x does not have any points where it is undefined because it is a linear function ( a line). The answer is all real numbers or (-infinity,infinity)
