7. Determine the equation of the tangent to the graph of y = - *3 + 5 x2 +2x + 3 at the point (1, 1).(five marks) a. Y = =X+ c. y = 3x - 2 b. y =-x+2 d. Y = - 4 x+ aly 8. The position function of an object is given by s(1) = 15 - 25, where time, t, is in seconds, distance, s, is in metres, and $ 2 0. What is the acceleration at the instant the object is momentarily at rest? (five marks) a. 5 m/s2 c. 10 m/s2 b. -9.8 m/s2 d. 2 m/s2
