Question

let f(x)=2.912345x^2+3.131579x-0.099999 To simplify approximation of f, write a quadratic function g(x) with integer coefficients that closely models f(x) for -10 < x <10

Answer 1

let f(x) = y, use quadratic formula to find x, then substitute f(x) for g(x)

Answer 2

\[g(x)=3x^2+3x\]

Answer 3

2.912345 is closest to the integer, 3.
3.131579 is closest to the integer, 3.
0.099999 is closest to the integer, 0.

Answer 4

how would you compute g(4) & f(4) ?
