The line `y = m x + 1`is a tangent to the curve `y^2=4x`if the value of m is
(A) 1
(B) 2
(C) 3
(D) `1/2`

Explanation

To determine the value of \( m \) for which the line \( y = mx + 1 \) is a tangent to the curve \( y^2 = 4x \), we can follow these steps:

### Step 1: Substitute the line equation into the curve equation
We start with the line equation:
\[ y = mx + 1 \]
We substitute this into the curve equation \( y^2 = 4x \):
