1.
sqrt(4 - x^2)
4 - x^2 ≥ 0
4 ≥ x^2
±2 ≥ x
or
-2 ≥ x ≥ 2
2.
50 / tan(27°) ≈ 98.13 yds

f(x) = ?(c - x²) all of us be attentive to that we could choose for a cost of c such that the function can't tackle any values of x decrease than -6 and greater suitable than 6. be conscious that a cost of 36 for c works right here.
