Answer:

The range is {9,15,19}  

Step-by-step explanation:

f (x) = 2x + 5

Let x = 2

f (2) = 2*2 + 5 = 4+5 = 9

Let x = 5

f (5) = 2*5 + 5 = 10+5 = 15

Let x = 7

f (7) = 2*7 + 5=14+5 = 19

The domain is {2,5,7}

The range is {9,15,19}  

Answer:

i think what you wrote is that the domain is 2 to 5.7.

so you plug in these two numbers inside the equation cause domain means the distance in the x axis so this is how it goes.

2(2) + 5 = 9

2(5.7) +5= 16.4

so the range is 9 to 16.4
