Given g(x) = –2x + 1, find g(-1).

g(-1) =3

Step-by-step explanation:

g(x) = –2x + 1,

Let x = -1

g(-1) = –2 *-1 + 1

        = 2 +1

         = 3

3

Step-by-step explanation:

We just have to plug in -1 for x which gives us -2 * (-1) + 1 = 2 + 1 = 3.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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.
