Alfred is practicing typing. the first time he tested himself, he could type 30 words per minute. after practicing for a week, he could type 33 words per minute. after two weeks he could type 36 words per minute. based on this pattern, predict how fast alfred will be able to type after four weeks of practice.

42 words per minute

Step-by-step explanation:

Weeks(x)          Words per minute(y)

0                              30

1                               33

2                              36

To find the function we will use two point slope form.

  ---A

Substitute the value in A

Thus the equation represents the situation :

Where y is the words per minute

x is the number of weeks

Now we are supposed to find how fast Alfred will be able to type after four weeks of practice.

Substitute x = 4

Hence Alfred will be able to type 42 words per minute after four weeks of practice.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
