If dy dx =3 then y is equal to : - Vidyadip

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.

$3x + c$

$\frac{\text{dy}}{\text{dx}}=3$
$\text{dy}=3\text{dx}$
$\int\text{dy}=\int3\text{dx}=3\text{x}+\text{c}$
$\therefore\text{y}=3\text{x}+\text{c}$
