Find the derivative of f(x) = 7x + 4
2 answers:
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:
7 d/dx[x^4]
Step-by-step explanation:
Since 7 is constant with respect to x, the derivative of 7x^4 with respect to x is 7 d/dc [x^4]
