Question

Given the equation y = 2(3^x) - 1, state the domain, range, x-intercept(s), y-intercept(s) and asymptote(s).

Answer 1

the domain is all acceptable values of "x"; inthis case, all real numbers (-inf,inf)

Answer 2

the range is all possible outcomes from inputing the domain values:

range: anything above -1 (-1,inf)

Answer 3

that range might be off.....gotta recall what the graph looks like :)

Answer 4

when x = 0; y=1....yint = 1

Answer 5

the range is valid... (-1,inf)

the xint is when y=0...y = 0 when 3^x = 1/2...so whatever that value is... :)
