Do anyone know how to solve this problem

The domain is .

Step-by-step explanation:

Let .

Since we have a fraction, we need to make sure that its denominator isn't zero, since division by zero isn't defined. This means that:

On the other hand, there's also a square root, whose argument can't be negative. This means that:

So the domain is:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

265 words per minute

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

answer: the first graph
