Find the domain, vertical asymptotes, and horizontal asymptotes of the function. f (a) = 2+7 x2 -49 Enter the domain in interval notation. To enter oo, type infinity. To enter U, type U. Domain: The fields below accept a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x +1; x - 1). The order of the lists do not matter. Vertical asymptotes: 7\f\"him an equation for a rational function with the given characteristics. Vertical asymptotes at a: : 4 and a: : 6, m-intercepts at (3, 0) and (1, 0), horizontal asymptote at y = 4 Enclose numerators and denominators in parentheses. For example, (a, b)/ (1 + n). Include a multiplication sign between symbols. For example, a * 2:. Hit): E The volume, V, of a sphere in terms of its radius, r, is given by V (r) : ia'r'r3. Express 1' as a function 3 of V, and find the radius of a sphere with volume of 250 cubic feet. Round your answer for the radius to two decimal places. Enclose numerators and denominators in parentheses. For example, (a, b)/ (1 + n). Include a multiplication sign between symbols. For example, a. * qr. ab sin (a) 00 a [III 0 A sphere with volume 250 cubic feet has radius Number feet
