1) what is function notions? 2) why is function notation used? 3) what does it mean by the expression f(x)?

1. function notation is the way a function is written.

2.the use of function notation makes it clear which is the dependent variable and which is the  independent variable in a functional relationship.

3.It means a formula, named f, has x as its input variable". It does not mean "multiply f and x''.

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.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
