Graph the function and identify all key characteristics f(x)=x^3-12x^2+45x-54
damaskus [11]

Answer:

We kindly ask you to see the explanation and the image attached below for further details.

Step-by-step explanation:

From Function Theory we know that third order polynomials are continuous functions with one relative minimum and one relative maximum and whose domain and range comprehends the set of all real numbers. Since the leading coefficient of the polynomial is positive, then two increasing intervals and only one increasing interval exist.

Now we proceed to graph the function and label each relevant information when possible.

Domain

Dom \{f(x)\} = \mathbb{R}

Range

Ran \{f(x)\} = \mathbb{R}

Zeros

x = 3 and x = 6

3. Which is the inverse of the function f(x) = 4x^2?
natali 33 [55]

Answer:

f^{-1}(x)=\frac{\sqrt{x}}{4}

Step-by-step explanation:

The inverse of the function is the "opposite" of a function, so to speak. One can find it by treating it like a literal equation with 2 variables, one now has to solve for the other variable presnet. In other words, treat the therm (f(x)) like another variable in the equation. Now one has to solve for (x) in terms of (f(x)).

f(x)=4x^{2}\\

Manipulate the literal equation with inverse operations;

f(x)=4x^{2}\\\sqrt{}\\\\\\\sqrt{f(x)}=4x\\/4\\\\\frac{\sqrt{f(x)}}{4}=x

Now switch the variables;

f^{-1}(x)=\frac{\sqrt{x}}{4}

The f^{-1}(x) signifies that the written function is the inverse of the original function.
