Find the equation of the tangent to the curve which is parallel to the line 4x – 2y + 5 = 0.
finding the slope of the tangent by differentiating the curve
equation of tangent is given by y – y1 = m(tangent)(x – x1)
now comparing the slope of a tangent with the given equation
m(tangent) = 2
since this point lies on the curve, we can find y by substituting x
therefore, the equation of the tangent is
