Second number line

Step-by-step explanation:

Intervals in the Number Line

When representing real intervals in the number line, we use solid lines that start from the lower or upper limit and end in the final number. If there is no limit, then we use an arrow pointing to plus or minus infinity.

If the endpoint is included in the interval, we place a filled circle, if it's not included, we use a hollow circle.

We want to show the interval , this means we must include the 11 and go up to positive infinity. The only number line with such characteristics is that on the second option.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

hope this !

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.
