Q16 of 149 Page 16

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
