Determine a a in each case. (a) a = (0, 1] in the lower limit topology on r. (b) a = {a} in x = {a, b, c} with topology {x, ø, {a}, {a, b}}. (c) a = {a, c} in x = {a, b, c} with topology {x, ø, {a}, {a, b}}. (d) a = {b} in x = {a, b, c} with topology {x, ø, {a}, {a, b}}. (e) a = (-1, 1) u{2} in the standard topology on r. (f) a = (-1, 1) u{2} in the lower limit topology on r. (g) a = {(x, 0) erp | xer} in r2 with the standard topology.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

true. i hope this ! go answer some of my newest

i dont know

step-by-step explanation:

the reason i dont know is because i have not taken this class and for that reason i haven't learned this stuff

hope i could
