Write in a short form as an indefinite integral and indicate the integrand and the variable of integration. The derivate of what function is x^2 + 4x.

Step-by-step explanation:

We can equate the expression x^2+4x to f(x) and specify the variable of integration , the integrand and the symbol simply like this ,

Let,

Where the integrand is f(x) , x is the variable of integration , c is the constant of integration , and ∫ is the symbol of integration.

The derivate of what function is x^2 + 4x?

To find that out we integrate the function because Integrating a differentiate is the process of obtaining the original process because Integrals are also called as Anti-derivatives.

So,

This is an indefinite integral which would result in an addition of a constant later on because it does not have limits. The variable of integration is x because there is only one variable present in this expression so naturally the variable of concern is x

so now we solve,

Where K is the constant of the indefinite integral.

answer: finding the extract measurements and knowing the points

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
