Check out our online quiz and test your understanding of Differentiation concepts, rules, and solve some simple questions for us.

• 1.

Differentiate y=3x4-5x

• A.

3x3-5

• B.

12x3-5

• C.

12x3+5

• D.

12x2

B. 12x3-5
Explanation
The correct answer is 12x3-5. This is the correct answer because when we differentiate the given function y=3x4-5x, we apply the power rule of differentiation which states that when differentiating a term with a variable raised to a power, we multiply the coefficient by the power and then decrease the power by 1. Therefore, when we differentiate 3x4, we get 12x3, and when we differentiate -5x, we get -5. Thus, the derivative of y=3x4-5x is 12x3-5.

Is differentiation of y=6x3-1 is 18x3 true or false?

• A.

True

• B.

False

B. False
Explanation
The differentiation of y=6x^3-1 is not equal to 18x^3. When we differentiate y=6x^3-1, the power rule states that the derivative of x^n is nx^(n-1). Therefore, the derivative of 6x^3 is 18x^2, not 18x^3.

Differentiate y=5/x2

• A.

5x2

• B.

-5x-3

• C.

-10x-3

• D.

10x-3

• E.

Option 5

C. -10x-3
Explanation
The given expression is y = 5/x^2. To differentiate this expression, we use the power rule of differentiation. The power rule states that when differentiating a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1). Applying this rule, we differentiate y = 5/x^2 as follows:
y' = (5)(-2)x^(-2-1) = -10x^(-3) = -10/x^3. Therefore, the correct answer is -10x-3.

• 4.

Differentiate y= -3x-5-10x+2

• A.

3x5-10x

• B.

-3x-6+10

• C.

15x-6-10

• D.

15x-5-10

C. 15x-6-10
Explanation
The given expression is a polynomial with two terms. To differentiate it, we can use the power rule, which states that the derivative of x^n is n*x^(n-1). Applying this rule to the first term, -3x, we get -3. For the second term, -10x, the derivative is -10. Therefore, the derivative of the given expression is 15x - 3 - 10, which simplifies to 15x - 6 - 10.

• 5.

Differentiate y=3x-4+6x-1

• A.

12x-1

• B.

-4x-5+6x-1

• C.

12x-5+6

• D.

-12x-5+6

• E.

Option 5

D. -12x-5+6
Explanation
The given expression is y=3x-4+6x-1. We can simplify this expression by combining like terms. Combining 3x and 6x, we get 9x. Combining -4 and -1, we get -5. Therefore, the simplified expression is 9x - 5. The answer -12x-5+6 does not match the simplified expression, so it is not the correct answer.

Rate this question:

• 6.

Differentiate y=5-13x2-4x3

• A.

26x-12x

• B.

-26x-12x2

• C.

-13x2-12x

• D.

26x2-12

• E.

Option 5

B. -26x-12x2
Explanation
The given expression is y=5-13x^2-4x^3. To differentiate this expression, we take the derivative of each term. The derivative of 5 is 0, the derivative of -13x^2 is -26x, and the derivative of -4x^3 is -12x^2. Therefore, the differentiated expression is -26x-12x^2.

Rate this question:

• 7.

Is differentiation of y=5x-2-12 is -10x-3 true or false?

• A.

True

• B.

False

A. True
Explanation
The given expression y=5x-2-12 can be simplified as y=5x-14. Therefore, the correct answer -10x-3 is false.

Rate this question:

• 8.

Differentiate y=4/x4

• A.

4x-5

• B.

4x5

• C.

16x-5

• D.

-16x-5

D. -16x-5
Explanation
The given expression is y = 4/x^4 - 4x - 5. To differentiate this expression, we can use the power rule for differentiation. The derivative of 4/x^4 is -16/x^5, the derivative of -4x is -4, and the derivative of -5 is 0. Combining these derivatives, we get -16/x^5 - 4. Simplifying further, we can rewrite this as -16x^-5 - 4, which is equivalent to -16/x^5 - 4. Therefore, the correct answer is -16x - 5.
