Answer:
-13/10
Step-by-step explanation:
It wont be -7/10 because to change a mixed number to an improper fraction, we multiply the whole number by the denominator and then add this product with the numerator.
Answer:
![\frac{x^3}{3}+2x^2 + K\\\\](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E3%7D%7B3%7D%2B2x%5E2%20%2B%20K%5C%5C%5C%5C)
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,
![f(x)=x^2+4x\\\\F'(x)=f(x)\\\\\int f(x)\ dx=F(x) + K](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B4x%5C%5C%5C%5CF%27%28x%29%3Df%28x%29%5C%5C%5C%5C%5Cint%20f%28x%29%5C%20dx%3DF%28x%29%20%2B%20K)
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,
![\int\ x^2+4x \ dx](https://tex.z-dn.net/?f=%5Cint%5C%20x%5E2%2B4x%20%5C%20dx)
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,
![\int\ x^2+4x \ dx\\\\\frac{x^3}{3}+4(\frac{x^2}{2}) + K\\\\\frac{x^3}{3}+2x^2 + K\\](https://tex.z-dn.net/?f=%5Cint%5C%20x%5E2%2B4x%20%5C%20dx%5C%5C%5C%5C%5Cfrac%7Bx%5E3%7D%7B3%7D%2B4%28%5Cfrac%7Bx%5E2%7D%7B2%7D%29%20%2B%20K%5C%5C%5C%5C%5Cfrac%7Bx%5E3%7D%7B3%7D%2B2x%5E2%20%2B%20K%5C%5C)
Where K is the constant of the indefinite integral.
Answer:
f(x) = 2(x + 4)² - 2
Step-by-step explanation:
Equation of quadratic function whose vertex is (h, k),
f(x) = a(x - h)² + k
Equation of the function with vertex (-4, -2) shown in the graph will be,
f(x) = a(x + 4)² - 2
This graph is passing through a point (-6, 6) also,
6 = a(-6 + 4)² - 2
6 + 2 = a(-2)²
a =
= 2
Therefore, quadratic function is f(x) = 2(x + 4)² - 2
