yes
Finally got in I restarted
oh ok post your question and i will comeback :)
Heinz has a list of possible functions. Pick one of the g(x) functions below, show how to find the zeros, and then describe to Heinz the other key features of g(x). • g(x) = x^3 – x^2 – 4x + 4 • g(x) = x^3 + 2x^2 – 9x – 18 • g(x) = x^3 – 3x^2 – 4x + 12 • g(x) = x^3 + 2x^2 – 25x – 50 • g(x) = 2x^3 + 14x^2 – 2x – 14
Provide a rough sketch of g(x). Label or identify the key features on the graph.
g(x) = x^3 – x^2 – 4x + 4 The zeros are found by factoring the equation. x^2(x-1) - 4(x -1) = 0 (x^2 -4)(x-1) = 0 (x+2)(x-2)(x-1) = 0 x = 2, -2, and 1 The other key features are: g'(x) gives the slope g''(x) gives the concavity g'(x) = 0 will give the critical points g''(x) = 0 will give the point of inflection
Can you draw a rough sketch of it?
lemme see
Okay
