What is the domain of f(x)=^3 sqrt x?

tino4ka555 [31]

ANSWER

Domain is all real numbers.

EXPLANATION

We want to find the domain of the function,

$f(x) = \sqrt[3]{x}$

The domain of this function refers to all values of x that will make the function defined.

When we plug in all real values into the above function, there will be a corresponding functional value.

Therefore the domain is all real numbers.

Or

$x \in \: R$

Or

$( - \infty ,+ \infty)$

Exhibit 15-2A regression model between sales (y in $1000s), unit price (x1 in dollars) and television advertisement (x2 in dolla

Semmy [17]

Answer:

Sales are expected to increase positively.

Step-by-step explanation:

The model is y =7-3*X1+5*X2

Here, y is the depended variable and X1 and X2 are independent variable.

Holding the unit price constant X2 (television advertisement) is increase by $1 dollar

SSR= 3500

SSE=1500

So, TSS = SSR+SSE = (3500+1500) = 5000

Now r^2= 1 - (SSR/TSS) = 1 - (3,500/5,000) = 1 - 0.70 = 0.30

So, the sample correlation coefficient (r) = (0.3)^(1/2) = 0.547

We can conclude that sample correlation indicates a strong positive relationship.
