The tangent to the parabola x2 = 2y at the point (1, 1/2) makes with the x-axis an angle of 45° 0° 78° 10° 2 / 10 92. The two curves x3 – 3xy2 + 5 = 0 and 3x2y – y3 – 7 = 0 cut at right angles cut at left angles touch each other none 3 / 10 93. The tangent to the curve y = 2x2 -x + 1 is parallel to the line y = 3x + 9 at the point (2, 3) (1, 2) (2, 7) 0 4 / 10 94. The tangent to the curve y = x2 + 3x will pass through the point (0, -9) if it is drawn at the point (0, 1) (-3, 0) (-3, 50) 0 5 / 10 95. Find a point on the curve y = (x – 2)2. at which the tangent is parallel to the chord joining the points (2, 0) and (4, 4). (3, 1) (3, 41) (13, 1) 0 6 / 10 96. Tangents to the curve x2 + y2 = 2 at the points (1, 1) and (-1, 1) are parallel perpendicular intersecting but not at right angles none of these 7 / 10 97.
