Emily's homework is to read for more than 25 minutes every night.
1 minute = 60 seconds
25 minutes seconds
more than 25 minutes is more than 1,500 seconds
Options D and E give you times that are greater than 1,500 seconds, options A, B and C give you times that are less or equal to 1,500 seconds.
For this case we have the following table:
X F(x)
-1 -11
0 -1
1 9
From here, we look for the function f (x).
We then have that as the equation is linear:
Where,
We choose an ordered pair:
Substituting values:
Rewriting:
Thus, the function f (x) is:
On the other hand, the function g (x) is:
Answer:
The slope of f (x) is greater than the slope of g (x) (10> 5)
The intersection with the y axis of g (x) is greater than the intersection with the y axis of f (x) (1> -1)
