Which inequality statement best represents the graph?

f(x) ≤ 2x2 + 4x

f(x) ≥ 2x2 + 4x

f(x) ≤ –2x2 + 4x

f(x) ≥ –2x2 + 4x

The answer to your question is the second option f(x) ≥ 2x² + 4x

Step-by-step explanation:

In the graph, we observe that we need the up area of the parabola so the inequality must be ≥. From this observation, we discard the options one and three.

The last equation is a parabola that opens downwards not upwards as we notice in the graph so we discard the fourth option.

$9.41

step-by-step explanation:

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
