Create a function that has a derivative of f(x) = 2x + 1 at a given input value of your choice.
Taya2010 [7]
The opposite operation to taking a derivative is an integral. Integrate to find original function.

f(x) = x^2 + x + C

C is constant because we didn't have bounds on the integral. it lets you choose the input value let's say is just (1,0)

0 = 1 + 1 + C
- 2 = C

function at input value (1,0)
f(x) = x^2 + x - 2

now if you check by taking derivative is :
f' = 2x + 1

Find the quotient using polynomial long division:
Snowcat [4.5K]

(1) 50y^3=5y\cdot 10y^2, and

10y^2\cdot(5y-4)=50y^3-40y^2

Subtract this from 50y^3+10y^2-35y-7 to get a remainder of

(50y^3+10y^2-35y-7)-(50y^3-40y^2)=50y^2-35y-7

What we've done here is show that

\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+\dfrac{50y^2-35y-7}{5y-4}

We can keep going as long as the degree of the remainder's numerator is at least the same as the degree of its denominator.

Next, 50y^2=5y\cdot 10y, and

10y\cdot(5y-4)=50y^2-40y

Subtract this from the previous remainder to get a new remainder of

(50y^2-35y-7)-(50y^2-40y)=5y-7

which means

\dfrac{50y^3+10y^2-35y-7}{5y-4}=10y^2+10y+\dfrac{5y-7}{5y-4}

Finally, 5y=5y\cdot1, and

1\cdot(5y-4)=5y-4

Subtract this from the previous remainder to get

(5y-7)-(5y-4)=-3

So we end up with

\dfrac{50y^3+10y^2-35y-7}{5y-4}=\boxed{10y^2+10y+1}-\dfrac3{5y-4}

(the quotient is the expression in the box)

(2) Using the same process as before:

8m^4=2m\cdot4m^3

4m^3\cdot(2m+1)=8m^4+4m^3

(8m^4-4m^2+m+4)-(8m^4+4m^3)=-4m^3-4m^2+m+4

\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-\dfrac{4m^3+4m^2+m+4}{2m+1}

-4m^3=2m\cdot(-2m^2)

-2m^2\cdot(2m+1)=-4m^3-2m^2

(-4m^3-4m^2+m+4)-(-4m^3-2m^2)=-2m^2+m+4

\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-\dfrac{2m^2-m-4}{2m+1}

-2m^2=2m\cdot(-m)

-m\cdot(2m+1)=-2m^2-m

(-2m^2+m+4)-(-2m^2-m)=2m+4

\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=4m^3-2m^2-m+\dfrac{2m+4}{2m+1}

2m=2m\cdot1

1\cdot(2m+1)=2m+1

(2m+4)-(2m+1)=3

\implies\dfrac{8m^4-4m^2+m+4}{2m+1}=\boxed{4m^3-2m^2-m+1}+\dfrac3{2m+1}
