The quadratic function f is positive only in the intervals (-infinity, 0) and (10, infinity) f has a minimum value of -100. Determine the coefficients of f.

If square root x = -7, then x= -49 true or false

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.

If f(x)=3 over x+2 - square root x-3 then f(7)=
