Calculate the following limits assuming that: lim f(x) = 7, lim g(x) = 1 x-+4 x -+ (Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if the limit does not exist.) (a) lim (f(x) - 48(x)) = x++4 (b) lim (x2 f(x)) = x-+4 (c) lim f(x) x-+4 g(x) +3x x-+4 (d) lim (2g(x)4 - 8(x)3/2) =
