Select the correct answer. What is the domain of this radical function? a. [3, [infinity]) b. [-3, [infinity]) c. [1, [infinity]) d. [-1, [infinity]).

### Answers

The **domain **of a **function **is the set of input values the **function **can take

The **radical function **is not given; so, I will provide a general explanation

Assume the **radical function **is:

[tex]f(x) = \frac{1}{\sqrt{12- 2x}}[/tex]

The **denominator **of the above function cannot be negative.

So, we express the denominator as follows

[tex]12-2x > 0[/tex]

Subtract 12 from both sides

[tex]-2x > -12[/tex]

Divide both sides by -2

[tex]x < 6[/tex]

Let g be the function given by g(x)=x2ekx, where k is a constant. For what value of k does g have a critical point at x=23?.

### Answers

It looks like we have

[tex]g(x) = x^2 e^{kx}[/tex]

If x = 23 is a critical point of g(x), then

[tex]g'(x) = 2x e^{kx} + kx^2 e^{kx} = (kx^2 + 2x) e^{kx}[/tex]

[tex]\implies g'(23) = (23^2k + 46) e^{23k} = 0[/tex]

[tex]e^{23k}[/tex] is positive for all k, so we're left with

23² k + 46 = 0

23² k = -46

k = -46/23²

**k = -2/23**
