Compare the graphs of the functions listed below. function 1: y = 0.25x2 function 2: y = 4x2 function 3: y = -½x2 function 4: y = -16x2 the graph of is the widest

The graph of Function 1: y=0.25x^2 is the widest

Solution:

The widest graph is that with the smallest coefficient of x^2 in absolute value:

The coefficient of x^2 in funtion 1 in absolute values is 0.25

The coefficient of x^2 in funtion 2 in absolute values is 4

The coefficient of x^2 in funtion 3 in absolute values is 1/2=0.5

The coefficient of x^2 in funtion 4 in absolute values is 16

The smallest coefficient of x^2 in abolute value is in Function 1: y=0.25x^2

on edge its Function 1, then Function 4, and then narrower than, yw

Step-by-step explanation:

darn right!

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
