Question
  1. Write an equation of a cubic function f(x), with zeros at -5, 0, and 2, and end behaviour from second to fourth quadrant
  2.  The maximum number of x-intercepts you can expect the function f(x) = x^4 -2x^3 + 3x^2 -8x+1, to have is:
  3.  State the remainder when (x^3 -7x + 9) is divided by (x-2)
  4.  Does the function f(x) -5x^3+1  have even, odd, or no symmetry?
  5. State the horizontal and vertical asymptotes for the function: g(x) = 2x^2 + 1/ 3x^2 + 7x -6 = 2x^2 + 1/ (x+3) (3x-2)
  6. State the exact value of sin (5π/6)
  7. Give the period for the function y=2sin (3(x-π/4))
  8. Express cos(3π/4) as a ratio of the related acute angle π/4
  9. Use a compound angle formula to calculate the exact value of sin (5π/18) cos (π/9) -cos (5π/18) sin (π/9)
  10.  State the inverse of the function: y=5^x    
  11. Rewrite in exponential form logx = y=z
  12. Solve for x. State the exact value 2^x = 7, these are all apart of one question section so answer them all pls and ty
