WebExplanation of this problem:Example 2: The tangent to the curve y=x2 − 5x + 5 parallel to the line 2y = 4x + 1, also passes through a point. Find the coordinates of the point. Solution: dy/dx = 2x – 5 x=x1 = 2 2x1 = 7 ⇒x1 = 7/2 y1 = (49/4) – (35/2) + 5 = (49 – 70 + 20)/4 = -¼ y + ¼ = 2(x – 7/2) 4y + 1 = 8x – 28 ⇒ 8x – 4y ...
