Question

Assume log_b x = 0.42, log_b y = 0.39, log_b z = 0.74. using the properties of logarithm evaluate the logarithmic expression log_6(xy^2/6) A. 0.49 B. 0.46 C. 0.88 D. 0.8632 19. Find the equation of the parabola below. A. y = (x - 2)^2 - 3 B. y = -(x + 3)^2 + 2 C. y = -(x - 2)^2 - 3 D. y = -(x - 3)^2 20. Find x- and y-intercept (s) of the graph of the polynomial function f(x) = -4x^3 - 4x A. x - intercepts = (0,0), (1,0), (-1,0); y - intercepts = (0,0) B. x - intercepts = (0,0); y - intercepts = (1,0),9-1,0) C. x - intercepts = (1,0), (-1,0); y - intercepts = (0,0) D. x - intercepts = (0,0); y - intercepts = (0,0), (4,0), (-4,0) 21. The points of intersection of graphs y = x^2 - 2x + 1 and y = x + 5 are A. (4,9) and (-1,4) B. (-4,1) and (1,6) C. (-3,2) and (2,7) D. (3,8) and (-2,3)

y intercept = (0,0)

21.

x =4 and -1

points are (4,9) and (-1,4)
