How do I find the domain and range of a graph?​

Mathematics

The domain is the x-axis and the range is the y-axis.

To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.

To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.

<u>Final Answer</u>

D: -3 ≤ x ≤ 3

R: -4 ≤ x ≤4

This question would actually go under physics

Assuming that the model rocket goes straight up into the air and not at an angle, you can calculate for the maximum height by finding how long it takes for the velocity of the rocket to reach 0.

This can be calculated using the equation
t = (v sinx) /g
where t=time, v=velocity at zero seconds, x=angle of launch, g=gravity

Since we are assuming that the rocket flies straight up, the angle would be 90º, so sinx would be equal to 1.

That reduces are equation to 
t = v / g
g=9.81 m/s^-2

So we need to convert gravity to feet/second^-2 and divide 160 by g, 160 being the initial velocity.

g=9.81 m/s^-2 = <span>32.2 ft/s^-2

160/32.2 ≈ 4.97 seconds

For what value of x is the equation 2(x-4)+x=10 true?
Snowcat [4.5K]

Answer:

x=6

Step-by-step explanation:

2(x-4)+x=10

expand into 3x-8

add 8 to both sides 3x-8+8=10+8

simplify 3x=18

divide both sides by 3 3x/3=18/3

simplify x=6
