Question

Find the derivative of f(x) = 7x + 4

Answer 1

F(x) = 7x + 4
Answer: f’(x)=7

Steps:
1. Take the derivative of both sides

2. Use differentiation rule

3. Find the derivative

4. Removing doesn't change the value, so remove it from the expression

5. Solution f’(x)=7

Answer 2

7 d/dx[x^4]

Explanation:

Since 7 is constant with respect to x, the derivative of 7x^4 with respect to x is 7 d/dc [x^4]
