What are the domain,
range, and asymptote of h(x) = 6^x- 4?
domain: {x | x is a real number}; range: (y | y > 4}; asymptote: y = 4
domain: {x | x is a real number};
range: {y l y > -4}; asymptote: y = -4
domain: {x | x > -4}; range: {y I y is a real number}; asymptote: y = 4
domain: {x | x > 4}; range: {y I y is a real number}; asymptote: y =-4
