It's A. When you reduce between the x exponents in the original you get an xcubed on top. In A, when you reduce between the x exponents you get xcubed on bottom and they cancel each other out.
Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
Answer:
-1/2
Step-by-step explanation:
Using rise/run we can go up 1 and over 2 to get to the next point. When a line is graphed going from top left down to the right, it is negative.
I hope that helps u out!!
Good luck! :)
The domain of the function f(x)=x+10 is (-∞, ∞) and for the function g(x)=x² is (-∞, ∞).
<h3>What is meant by domain?</h3>
If a formula specifies a real function f, it may not be defined for some values of the variable. The natural domain or domain of definition of f is the set of real numbers on which the formula can be evaluated to a real number in this case. A partial function is often referred to just as a function, and its natural domain is referred to simply as its domain.
Given, f(x) = x + 10
g(x)=x²
The domain for the function f(x)=x + 10
So, the domain of f(x)=x+10 is (-∞, ∞)
The domain for the function g(x)=x²
The expression's domain is only real numbers, with the exception of places where it is undefined. Because there is no real number in this scenario, the expression is undefined.
So, the domain of the function g(x)=x² is (-∞, ∞)
