.beteihe the équatióh of the line passing through the points (2,1) and (4.7). The and y-intercept are: L0 Slope y-intercept (A) 3 (0, 7) 0, 5/3) D) 3 (E) None of these. 7. Which of the following statements is/are equivalent to: "x + 3 is a factor of the polynomial p(x"? 3-3 (1) x = 3 is a solution of p(x) 0 (2) x-3 is a zero of p(x) (3) (-3,0) is an x-intercept of p(x) (B) 2 only (C) 3 only A) 1 only (D) 1 and 3 only (E) 2 and 3 only (F) All of them 8. Determine the vertical asymptote?s), is any, for 4x2-1 (A) (B) x =- (C) x = (D) (E) x =-1 (F) None of these 9, which of the following is/are correct? Assume that a > 0 and a 1. (1) logb(1-0 (2) logb(0)-1 (3) In(1)-e (4) In (A) None of them (B) 4 only (C) 1 and 4

Explanation / Answer

Solution:

(E) 2 and 3 only

Reason: x+3 is factor that means x = -3 is root of p(x)

at (-3,0) p(x) touches x axis therefore it makes x intercept
