PART 1: Answer these questions
- A box is to be constructed from a sheet of cardboard that is 20 cm by 60 cm, by cutting out squares of length x by x from each corner and bending up the sides. What is the maximum volume this box could have?
- Find the amplitude and period of y = –3cos(2x + 3).
Use your calculator to graph the function and state its symmetry.
Find the first positive x-intercept using your calculator’s zero function.
- Find two functions f(x) and g(x) such that f[g(x)] = x but g[f(x)] does not equal x.
- State the vertical, horizontal asymptotes and zeros of the rational function, f(x) = x2+3x+2×2+5x+4.
Why is there no zero at x = –1?
- Give an example and explain why a polynomial can have fewer x-intercepts than its number of roots.
