70 72 76 90 what will go before 90

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.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
