Graph each absolute value function. State the domain, range, and y-intercept.
SVEN [57.7K]

Answer:

The domain is  (-\infty,\infty) and its range is [3,\infty).

The y-intercept is (0,3).

Step-by-step explanation:

Consider the parent function y=|x|. Its domain is x\in (-\infty,\infty) and its range is y\in [0,\infty).

The graph of the function y=|x|+3 is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the  domain and will change the range of the function, thus the domain is  (-\infty,\infty) and its range is [3,\infty).

To find th y-intercept you have to find y at x=0:

y=|0|+3=3.

Hence, the y-intercept is (0,3).

Find the Volume<br> I need correct answer
abruzzese [7]

Answer:

70 cm^3; 1000 cm^3; 343 cm^3; 30 cm^3; 48 cm^3

Step-by-step explanation:

to find the volume to all of these shapes you can just multiply all the sides together

one looks like this

2 * 5 * 7 = 70

70 is the answer for the first one

you repeat this 4 more times

since a cube has all equal sides for 2 and 3 you can just cube your side length

10^3 = 1000

7^3 = 343

afterwards since they are all just rectangular prisms you can just multiply all the sides together

1 * 5 * 6 = 30

4 * 6 * 2 = 48

those are your answers

dont forget to add ^3 behind the cm
