Function f is shown in the table. what type of function is function f?

It is an exponential function.

Step-by-step explanation:

From the given table it is notices than the vale of y is not increasing at the same rate, therefore the function is not linear.

The value of y increases at the increasing rate, therefore the table may be shows the exponential function.

The general for of exponential function is

At x=1, y=2.

         .... (1)

At x=-1, y=32.

   .... (2)

Multiply equation (1) and (2).

put this value is equation (1)

Therefore the function is

Now put all values of x one by one. If all the points satisfied by this equation, then the table shows the exponential function.

At x=-6,

At x=-3,

At x=3,

Since all the points satisfied by this equation, then the table shows the exponential function.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
