MCQ
If $\frac{\text{dy}}{\text{dx}}=3$ then y is equal to:
  • A
    3x
  • B
    0
  • 3x + c
  • D
    $\frac{\text{x}}{3}+\text{c}$

Answer

Correct option: C.
3x + c
$\frac{\text{dy}}{\text{dx}}=3$
$\text{dy}=3\text{dx}$
$\int\text{dy}=\int3\text{dx}=3\text{x}+\text{c}$
$\therefore\text{y}=3\text{x}+\text{c}$
