◉ 5. f(t) = 4/3-t. Answer: *domain=(-∞,3) U (3,∞)*; y in range and y =
- t, t<3 => 3-t > 0 => - t > 0, or if t > 3 => 3 - t < 0 => 4/3 - t <
0 => y can any nonzero real number => *range=(-∞,0) U (0,∞)*

◉ 9. Express the area and perimeter of an equilateral triangle as a
function of the triangle's side length x. Answer: Perimeter: p(x) = 3x
Area: a(x) = ( 1/2 ) ( base ) ( height ) = (1/2)(x) ( √3/2(x) ) = ( √3/4 )( x²
)
