I need help finding the domain and range of a graph

Mathematics
1 answer:
Troyanec [42]3 years ago
8 0

Hey there!

To find the domain of a graph, you look for the points furthest to the left and furthest to the right. For example, you could have the points (-3,-4) and (9,10). When looking for the domain, you only focus on the x-values. Therefore, your domain would be (-3,9).

To find the range, you find the highest and lowest points on the graph, and look for the y-values. Say the (-3,-4) and (9,10) are also the lowest and highest points on your graph. Therefore, your range would be (-4,10)

I hope this explanation helps!

A nurse sees 24 patients in 5 hours. At this rate, approximately how many patients will the nurse be able to see in a 8-hour per
Vikki [24]

Hi!

We will solve this using proportions, like this:

24 patients in 5 hours

x patients in 8 hours

_________________

x = (24*8)/5

x = 192/5

x = 38,4

The nurse will be able to see 38,4 patients in a 8-hour period, but because it's patients we are talking about, living things which can't be represented in decimal form, the nurse will be able to see approximately 38 patients in a 8-hour period.

Hope this helps!

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)

What is an equation of the line that passes through the point (3, 3) and is parallel to
Lena [83]

Answer:

y=6x

Step-by-step explanation:

The formula you use is y=mx+b you get 4x-3y=21 you add 3 to 3y and 21 then you cancel out the 3's 4x goes down and then you add 21+3 which equals 24 then you divide it all by 4 except y, you drop the y down and you should get y=6x

Hope you get it right
