D/dx(x² + 2x - 4) = 2x + 2

d/d (x² + 2x - 4) 

= d/dx (x²) + d/dx(2x) - d/dx(4)

= d/dx(x^2) - d/dx(2x) = 2x (due to power rule)

Replug in to equation
d/dx (2x) = 2

Take the constant out

d/dx (x) = 1

apply the common derivative

2 x 1

simplify 

2 x 1 = 2


d/dx(4) = 0

d/dx(4)

drivative of a constant = 0

= 2x + 2 - 0

Simplify:
2x + 2

2x + 2 is your answer


hope this helps

Let's take the derivative of each term one by 1

x^2
Apply the power rule for derivatives.
2x^(2-1) = 2x
You get 2x.

2x
Apply the power rule (x^1) and the constant multiple rule.
2 * x^(1-1) = 2 * x^0 = 2
You get 2.

-4
The derivative of a constant is 0.

Put that together and you get 2x + 2

Have an awesome day! :)

14.9. this is because 8 is in the tenth place, and the next number is five. for numbers greater than 4, you round up, for four or less, you stay the same.

Order these from least to greatest 3 39/40 , 3 19/20 , 3 1/2
Lera25 [3.4K]

Hey!

First change all the fractions so that they have a common denominator: 40

3 \frac{39}{40} = 3 \frac{39}{40}

3 \frac{19 \times 2}{20 \times 2} = 3 \frac{38}{40}

3 \frac{1 \times 20}{2 \times 20} = 3 \frac{20}{40}

Now order them:

3 \frac{39}{40} , 3 \frac{19}{20} , 3 \frac{1}{2}

Good luck and hope this helps! :)
